Abstract
A sample and hold circuit for producing an output voltage the magnitude of which is representative of the peak magnitude of a sampled input signal. The sample and hold circuit comprises a unity gain amplifier having an input terminal to receive said input signal and a cascoded output section for sourcing current at an output terminal. A discharge circuit is provided which includes a cascoded section for sinking current at said output terminal. Each of said cascoded sections being coupled to a capacitive load for charging or discharging the capacitor respectively to provide said output voltage.
