Use Hybrid PMOS-NMOS Active Loads To Cut Substrate Noise In Differential Amplifiers

PMOS transistors are less vulnerable to substrate noise since they’re placed in separate wells; designers implement guard rings to attenuate the substrate noise propagation. However, substrate noise ...

Eliminate crossover distortion in rail-to-rail amplifier design

All operational amplifier (op-amp) datasheets have an input voltage range limitation called the common-mode range. Strictly speaking, the common-mode voltage is the average voltage on the two inputs ...

Where did all that racket come from?

Since arriving in the market, CMOS single-supply amplifiers have been beneficial to single-supply-system designers worldwide. Key players affecting the THD+N (total-harmonic-distortion-plus-noise) ...
