Abstract
A flip around amplifier circuit is provided that includes an amplifier having first and second amplification stages, a Miller capacitor, and a resistive element in series with the Miller capacitor, where an output line of the second amplification stage can be coupled to an output line of the first amplification stage through the Miller capacitor and the series resistive element. The circuit can include a feedback capacitor having a first plate coupled to an input line of the amplifier, and a flip around switch that can be operated so as to connect an output line of the amplifier to a second plate of the feedback capacitor. The circuit's classical transfer function can include a zero associated with the Miller capacitor and the series resistive element, and a pole associated with the feedback capacitor and the on-resistance of the flip around switch, where the zero is substantially equal to the pole.
