Abstract
A track-and-hold circuit includes: a transistor, in which a base is connected to a signal input terminal, a power supply voltage is applied to a collector, and an emitter is connected to a first signal output terminal; a transistor in which a base is connected to the signal input terminal, the power supply voltage is applied to a collector, and an emitter is connected to a second signal output terminal; capacitors; a constant current source; and a switch circuit alternately turning the transistors to an ON state in response to differential clock signals.
