摘要： Various approaches of receiving signals in integrated circuitry include implementing a voltage-mode passive mixer for down-converting the frequency of the received signals, a baseband output buffer, and a transconductance amplifier coupled between the voltage-mode passive mixer and baseband output buffer for presenting a high-impedance load to the voltage-mode passive mixer and shielding the baseband output buffer from a high-frequency feedthrough.

摘要： Various approaches of receiving signals in integrated circuitry include implementing two successive stages of signal manipulation and employing an interface having an AC coupling network and buffer circuits for decoupling the output impedance and common-mode level of the first stage of signal manipulation from the input impedance and common-mode level of the second stage of signal manipulation without degrading the performance of either stage.

摘要： Various approaches of adjusting a gain of received signals in integrated circuitry include implementing an open-loop source-degenerated amplifier having a pair of input devices for amplifying the received signals; boosting an effective transconductance of the input devices (e.g., using a pair of super-gm feedback loops); and setting a bias current of devices in the open-loop source-degenerated amplifier (e.g., using a constant-gm bias circuit.)
