Abstract: An amplifier biasing circuit that reduces gain variation in short channel amplifiers, an amplifier biasing circuit that produces a constant Gm biasing signal for short channel amplifiers, and a multistage amplifier that advantageously incorporates embodiment of both types of amplifier biasing circuits are described. Both amplifier biasing circuit approaches use an operational amplifier to equalize internal bias circuit voltages. The constant Gm biasing circuit produces a Gm of 1/R, where R is the value of a trim resistor value. The biasing circuit that reduces gain variation produces a Gm of approximately 1/R, where R is the value of a trim resistor value, however, the biasing circuit is configurable to adjust the bias circuit Gm to mitigate the impact of a wide range of circuit specific characteristics and a wide range of changes in the operational environment in which the circuit can used, such as changes in temperature.

Abstract: A two-pin transmit/receive switch design includes a switching component configured to selectively switch in elements for a transmit signal path and elements for a receive signal path. A capacitor in the transmit signal path may be switched out when receiving signals on the receive signal path. Being able to selectively switch out the capacitor allows the capacitor value to be selected for optimal operation during transmit mode. For example, insertion loss may be minimized. In addition, elements in the receive signal path may be optimized (e.g., impedance matching) without being affected by or affecting the optimization that was performed for the transmit signal path.
