Abstract
Provided is a track and hold circuit. The track and hold circuit includes: a CMOS FVF; a pair of first switches, each of the first switches being coupled between a corresponding one of differential signal inputs and a corresponding one of differential inputs of the FVF; a second switch coupled between differential outputs of the FVF; the FVF includes a pair of first transistors with gates being differential inputs of the FVF and sources being the differential outputs of the FVF, a pair of second transistors, a first current mirror transistor, a second current mirror transistor and a third switch; where a state of the second switch is controlled by a clock signal to be the same as a state of the first switches, and a state of the third switch is controlled to be complementary to the state of the second switch.
