ABSTRACT:
An electronic circuit is described for accurately and rapidly initializing long-time constant amplifiers and the like. More specifically, the circuit is designed to establish quiescent conditions in minimal time and with minimal settling in amplifiers or integrators with internal or external voltage offsets. In performing its initializing function, the circuit utilizes a relatively low resistance network which mirrors the resistive network of the amplifier device and provides a charging path for the integrating capacitor. At the same time, the output of the device is permitted to immediately attain its steady-state voltage amplitude. The present auxiliary network automatically compensates for input offset error, so that quiescent conditions may be established extremely rapidly. Finally, the initialization configuration taught by the invention is characterized by simplicity and a small increase in the component count.
