Patent number: 9543897Abstract: A method, an apparatus, and a system product for mixing radio frequency signals are provided. In one aspect, the apparatus is configured to perform switching of switches based on first, second, third, and fourth phased half duty clock signals.

Patent number: 8995505Abstract: Techniques for providing a transceiver with a sliding intermediate frequency (IF). In an aspect, a PLL generates a single local oscillator (LO) signal used for both up-conversion by a transmit (TX) signal path and down-conversion by a receive (RX) signal path, wherein the LO frequency is chosen as the TX carrier frequency. As the TX and RX carrier frequencies may generally differ by a variable amount, the RX signal path utilizing the (TX) LO frequency for down-conversion may be characterized as having a “sliding” IF. To accommodate the sliding IF receiver architecture, specific processing functions such as charge sampling, discrete-time analog band-pass filtering, and sub-sampling analog-to-digital conversion (ADC) are described.Type: GrantFiled: November 30, 2012Date of Patent: March 31, 2015Assignee: QUALCOMM IncorporatedInventors: Faramarz Sabouri, Alberto Cicalini

Patent number: 8963611Abstract: Exemplary embodiments disclosed are directed to power and impedance measurement circuits that may be used to measure power and/or impedance are described. A measurement circuit may include a sensor and a computation unit. The sensor may sense (i) a first voltage signal across a series circuit coupled to a load to obtain a first sensed signal and (ii) a second voltage signal at a designated end of the series circuit to obtain a second sensed signal. The sensor may mix (i) a first version of the first sensed signal with a first version of the second sensed signal to obtain a first sensor output and (ii) a second version of the first sensed signal with a second version of the second sensed signal to obtain a second sensor output. The computation unit may determine the impedance and/or delivered power at the designated end of the series circuit based on the sensor outputs.Type: GrantFiled: October 16, 2009Date of Patent: February 24, 2015Assignee: QUALCOMM IncorporatedInventors: Puay Hoe See, Gary J.

Patent number: 8570076Abstract: A parallel path frequency divider (PPFD) includes a low power frequency divider and a high speed latch. A first portion of an oscillating input signal present on an input node of the PPFD is communicated to the divider and a second portion is communicated to the latch. The divider generates a frequency divided enable signal that is communicated to the latch. The latch generates a divided down output signal based on the oscillating input signal and the enable signal. The output signal is insensitive to phase noise present on the enable signal as long as the phase noise on the enable signal is less than one-half of the period of oscillation of the oscillating input signal. Because the noise generated by the low power frequency divider is not propagated to the output signal generated by the PPFD, the PPFD generates low noise, frequency divided signals with relatively low power consumption.Type: GrantFiled: July 1, 2010Date of Patent: October 29, 2013Assignee: Qualcomm IncorporatedInventors: Gary L. Brown, Alberto Cicalini, Dongjiang Qiao
