ABSTRACT:
A track and hold circuit is disclosed which may be used in high speed analog to digital conversions. The circuit includes a control transistor which keeps the circuit's input transistor in a conductive state even when the circuit is in hold mode. As a result, the track and hold circuit achieves a high switching speed while minimizing input voltage spikes.
