Abstract

A track and hold circuit is introduced, which includes a input buffer, a unit gain amplifier, a sampling switch, a current source, a driving NPN transistor and a over-driven protecting circuit. The over-driven protecting circuit is introduced to prevent the transistor of sampling switch from getting into linear working region. As a result, the sampling rate is improved dramatically. Meanwhile, two-stage insulation is adopted to prevent the incoming signal to disturb the holding signal on the sampling capacitor.
