Push-pull amplifiers improve second-order intercept point
Nov 1, 2005
By Radhakrishna Setty Wideband communications systems have signals occupying multi-octave frequency ranges. Such signals, when amplified in conventional amplifiers, can be distorted due to the second-order products generated inside the amplifier. An ideal push-pull amplifier can cancel the internally generated products and preserve the signal quality. ...
