ABSTRACT:
A low distortion differential sampler circuit implemented in GaAs is provided. The sampler circuit constitutes an on/off switching circuit rather than a sample and hold circuit. Elimination of the holding capacitor results in shorter switching times and reduced error. The sampler implements a differential, balanced architecture which compensates for clock signal feed through. The sampler circuit includes a three-stage, AC coupled GaAs pre-amplifier which provides a complementary clock signal to drive the sampler and sets the DC levels.
