Abstract
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-gfeedback loops); and setting a bias current of devices in the open-loop source-degenerated amplifier (e.g., using a constant-gbias circuit).
