  • Patent number: 8600300
    Abstract: Aspects of a method and system for single chip WLAN and Bluetooth radios on a single CMOS substrate are presented. Aspects of the system may include a WLAN receiver circuit within a substrate of a single chip that enables reception of WLAN signals, and a Bluetooth receiver circuit within the same substrate that enables reception of Bluetooth signals. The WLAN receiver circuit and Bluetooth receiver circuit may utilize a single low noise amplifier circuit that enables reception of the WLAN signals and Bluetooth signals. Aspects of the system may also include a WLAN transmitter circuit within a substrate of a single chip that enables transmission of WLAN signals, and a Bluetooth transmitter circuit within the same substrate that enables transmission of Bluetooth signals. The WLAN transmitter circuit and Bluetooth transmitter circuit may utilize a single power amplifier circuit that enables transmission of the WLAN signals and Bluetooth signals.

  • Publication number: 20130109326
    Abstract: A radio frequency (RF) transceiver includes an RF receiver having an RF receiver path that processes a received signal to generate inbound data, the receiver path having an RF front-end. A power amplifier calibration module generates power amplifier calibration signals in a calibration mode of operation, and generates power amplifier pre-distortion parameters in response to a calibration feedback signal. An RF transmitter processes output data to generate a transmit signal based on the power amplifier pre-distortion parameters in a transmit mode of operation and processes the power amplifier calibration signals to generate an amplified calibration output in the calibration mode of operation. A power amplifier calibration feedback path generates the calibration feedback signal, separate from the RF front-end, in response to the amplified calibration output.

  • Patent number: 7809408
    Abstract: Aspects of a method and system for a power switch with a slow in-rush current are presented. Aspects of the system may include at least one resistive component, which is coupled between an input control signal and an output stage circuit of a power switch circuit, so as to limit a peak transient current level, which may result from in-rush current delivered by the power switch circuit to a load impedance circuit during a transient time interval during which a voltage level across the load impedance circuit may rise or fall from an initial voltage level to a quiescent voltage level.
