Abstract

See full text

A method operates by receiving an input signal; transforming the input signal into a first transformed signal of a common-mode voltage equal to a first bias voltage; transforming the input signal into a second transformed signal of a common-mode voltage equal to a second bias voltage; detecting a peak of the first transformed signal and making the first bias voltage equal to a sum of a first DC (direct current) voltage and a first dynamic voltage; detecting a valley of the second transformed signal and making the second bias voltage equal to a sum of a second DC voltage and a second dynamic voltage; amplifying the first transformed signal into a first output signal across a first load using a N-type cascode amplifier; and amplifying the second transformed signal into a second output signal across a second load using a P-type cascode amplifier.
