Abstract

This paper presents a simple circuit technique to reduce gain variability with temperature in cascode amplifiers using a body-biasing scheme, and at the same time, enhance the overall gain of the amplifier. Simulation results of a standard telescopic-cascode amplifier, in two different nanoscale CMOS technologies (130 nm and 65 nm) show that it is possible to obtain supply-and-temperature-compensation. The simulated DC gain has low variability (below ± 0.5 dB) while it is enhanced by 3 dB. The required auxiliary biasing circuit dissipates less than 5% of the main amplifier circuit.
