Patent number: 8385985Abstract: Method for reducing power consumption in a multimode device is disclosed. The multimode device includes a COMM1 component and a COMM2 component. In one aspect, a COMM1 component may be a UWB component and a COMM2 component may be a CDMA component. According to a disclosed embodiment, the time for a next scheduled COMM1 wakeup process to be performed by a COMM1 module is established. Thereafter, if the next COMM1 wakeup process is scheduled to be performed before the next COMM2 wakeup process, a COMM2 wakeup process is synchronized to be performed by a COMM2 module at the same time as the next COMM1 wakeup process. Following, when the time arrives for the COMM1 module to perform the next COMM1 wakeup process, the COMM2 module also performs the COMM2 wakeup process.Type: GrantFiled: November 25, 2003Date of Patent: February 26, 2013Assignee: Qualcomm IncorporatedInventors: Joseph Patrick Burke, John M.

Publication number: 20130040555Abstract: A method and apparatus for eliminating transmit echo spurs is provided. The method includes the steps of: estimating a distortion effect applied to a transmit signal by a duplexer stop band. Next, the contribution of a primary component of the spur is estimated. An image component of the spur is estimated after the primary contribution has been estimated. The transmit echo is then subtracted from the composite desired signal by digitally subtracting the distortion effect, the primary component of the spur, and the image component of the spur, producing the desired composite transmit signal without the transmit echo.Type: ApplicationFiled: January 16, 2012Publication date: February 14, 2013Applicant: QUALCOMM INCORPORATEDInventors: Roberto Rimini, Peter D.

Publication number: 20120286874Abstract: A Positive Feedback Common Gate Low Noise Amplifier (PFCGLNA) has positive feedback transistors and input transistors that are of the same conductivity type. Making the positive feedback and input transistors of the same conductivity type reduces sensitivity to process variations. Noise generated by the positive feedback transistors is used to cancel noise generated by the input transistors. In one embodiment, the PFCGLNA: 1) is tunable to have a substantially constant input impedance for any frequency in a wideband frequency range from 680 MHz to 980 MHz, and 2) has a noise figure less than 2.2 dB over the entire wideband frequency range. The input impedance of the PFCGLNA can be tuned to match a source that drives the PFCGLNA by setting a multi-bit digital control value supplied to a digitally-programmable tank load of the LNA.Type: ApplicationFiled: May 13, 2011Publication date: November 15, 2012Applicant: QUALCOMM INCORPORATEDInventors: Namsoo Kim, Joseph Patrick Burke

Publication number: 20120230176Abstract: A method and apparatus for eliminating receive band noise in a communication system is provided. The method comprises sensing a transmit signal at a receive frequency, wherein the signal sensed is a bleed over signal from a transmit signal. The sensed bleed over signal is then digitized using a secondary receiver. This secondary receiver utilizes a separate path from the primary receive path. The next step in the method is to estimate the linear distortion, delay, attenuation in the sensed bleed over signal. Next, compensation for the linear distortion, delay, and attenuation are performed on the sensed bleed over signal. The sensed, digitized, and compensated bleed over signal is then cancelled from the primary receive path.Type: ApplicationFiled: March 7, 2012Publication date: September 13, 2012Applicant: QUALCOMM INCORPORATEDInventors: Christos Komninakis, Joseph Patrick Burke, Daniel Fred Filipovic

Publication number: 20120140860Abstract: A method and apparatus for a non-linear adaptive scheme for transmit out of band emission cancellation is provided. Embodiments disclosed herein provide a method for removing unwanted transmitter emissions from a composite received signal. The method performs the steps of: extracting the I and Q samples from a modulator output; inputting the I and Q samples to a non-linear filter; applying weights to the non-linear filter outputs, combining the non-linear filter outputs to generate a broadband emission estimate; selecting a portion of a transmit emission in a desired portion of a receive band; subtracting an output of the non-linear filter from a composite signal; and feeding back a residual error to the non-linear filter; adapting the non-linear filter iteratively.Type: ApplicationFiled: December 1, 2011Publication date: June 7, 2012Applicant: QUALCOMM INCORPORATEDInventors: Roberto Rimini, Mohammad Omer, Joseph Patrick Burke, Peter D.

Patent number: 7994850Abstract: A discrete time analog filter suitable for use in a receiver and other electronics devices is described herein. In one exemplary design, an apparatus may include a transconductance amplifier, a sampler, and a discrete time analog filter. The transconductance amplifier may amplify a voltage input signal and provide an analog signal. The sampler may sample the analog signal and provide analog samples at a sampling rate. The discrete time analog filter may filter the analog samples and provide filtered analog samples either at the sampling rate for a non-decimating filter or at an output rate that is lower than the sampling rate for a decimating filter. The discrete time analog filter may also filter the analog samples with either equal weights for a rectangular filter or at least two different weights for a weighted filter.Type: GrantFiled: June 25, 2008Date of Patent: August 9, 2011Assignee: QUALCOMM, IncorporatedInventor: Joseph Patrick Burke

Publication number: 20110069749Abstract: Techniques for correcting for memory effects of a transmitter are described. In an exemplary design, a receiver obtains input samples including a desired signal transmitted by a transmitter having memory effects. The receiver performs nonlinear equalization on the input samples to obtain first equalized samples, performs linear equalization on the input samples to obtain second equalized samples, and determines output samples based on the first and second equalized samples. The nonlinear equalization corrects for the memory effects and nonlinearities of the transmitter and possibly nonlinearities and memory effects of the receiver. The receiver may jointly determine coefficients for both linear and nonlinear equalization based on an adaptive algorithm. The receiver processes (e.g., demodulates and decodes) the output samples to recover data sent in the desired signal by the transmitter.Type: ApplicationFiled: September 24, 2009Publication date: March 24, 2011Applicant: QUALCOMM INCORPORATEDInventors: Aracely Forrester, Philip David Coan, Paul Draxler, Roberto Rimini, Bruce Judson, Joseph Patrick Burke

Publication number: 20110040818Abstract: A discrete time (DT) lowpass filter having various advantages is described. In an exemplary design, the DT lowpass filter includes a decimating DT filter (which may include a passive DT FIR filter and/or a passive DT IIR filter) and an active DT filter. The decimating DT filter receives a first DT signal at a first sample rate, filters and decimates the first DT signal by a factor of N, and provides a second DT signal at a second sample rate lower than the first sample rate. N may be greater than one. The active DT filter filters the second DT signal and provides a third DT signal at the second sample rate. A sampler samples a continuous time signal and provides the first DT signal. The sampler may further double the voltage of the first DT signal relative to the voltage of the continuous time signal.Type: ApplicationFiled: August 14, 2009Publication date: February 17, 2011Applicant: QUALCOMM INCORPORATEDInventors: Russell John Fagg, Joseph Patrick Burke

The LNTA amplifies a received RF signal and provides an amplified RF signal. The discrete time sampler samples the amplified RF signal (e.g., with multiple phases of a sampling clock) and provides first analog samples. The passive discrete time circuit decimates and filters the first analog samples and provides second analog samples. The switched capacitor amplifier amplifies the second analog samples and provides third analog samples. The discrete time receiver may further include a second passive discrete time circuit, a second switched capacitor amplifier, and an analog-to-digital converter (ADC) that digitizes baseband analog samples and provides digital samples. The discrete time receiver can flexibly support different system bandwidths and center frequencies.Type: ApplicationFiled: December 30, 2008Publication date: July 1, 2010Applicant: QUALCOMM INCORPORATEDInventors: Joseph Patrick Burke, Chengzhi Pan, Russell John Fagg
