ABSTRACT:
There is disclosed a sample and hold circuit using a four diode bridge using a voltage source and a bridge and a storage capacitor and the voltage source to be sampled coupled to the other two opposite nodes of the bridge. Switches in the lines coupling the voltage and current sources to the bridge control whether the sample and hold circuit is sampling data or holding the sampled voltage. This arrangement is characterized by extremely low sample voltage acquisition time.
