Abstract
An amplifier with Miller-effect frequency compensation in which the Miller feedback capacitor is connected to an internal terminal of the amplifier having a low impedance, and shunt compensation circuitry is connected to an intermediate signal terminal that drives the output amplifier stage. The compensation circuitry, which includes serially coupled capacitive and resistive circuit elements, introduces a high frequency zero to cancel one of the high frequency complex poles introduced by the Miller feedback capacitor connection.
