Abstract
A replica biasing circuit is proposed which allows open-loop gain in CMOS amplifiers to be accurately set. The approach can be applied to both RF and IF amplifiers whereas resistive loads have to be employed to achieve high frequency and low noise performance. The simulated results show a sensitivity to process tolerances and temperature variations which is lower than that of traditional approaches
