kompensacja PVT - Opis:
- This paper presents a simple circuit technique to reduce gain variability with PVT variations in cascode amplifiers using a body-biasing scheme, while enhancing 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 the proposed compensated circuit amplifier exhibits a (DC) gain variability smaller (below ± 0.5 dB) than the original (uncompensated) circuit, while reaching a gain enhancement of about 3 dB. The required auxiliary biasing circuit dissipates around 5% of the main amplifier circuit.
