VOLTAGE GENERATOR

摘要

A voltage generator is disclosed. The voltage generator includes an operational amplifier, an offset voltage tuner, and an output stage circuit. The operational amplifier receives an input voltage and adjusts an offset voltage of the operating amplifier according to a control signal. The offset voltage tuner provides the control signal. The output stage circuit generates an output voltage according to a voltage on an output terminal of the operational amplifier, and provides the output voltage to the operational amplifier.
