Having said that, Class AB amplifiers are one of the most preferred audio power amplifier designs due to their combination of reasonably good efficiency and high-quality output as they have low crossover distortion and a high linearity similar to the Class A amplifier design. , Lt L&C TECHNOLOGY INC. Power-constrained LNA design Problem: GHz-range, noise-matched CMOS LNAs consume significant power Solutions Current re-use with CMOS inverter (doubles V DD but still saves power Don't noise match, just bias at J opt Use external capacitor between gate and.
