description Apparatus and methods for frequency compensation of an amplifier are provided. In one embodiment, an integrated circuit (IC) includes an amplifier configured to amplify an input signal to generate an output signal. The IC further includes an output pad configured to receive an output signal from the amplifier and a control pad for controlling the closed-loop bandwidth of the amplifier. A compensation capacitor is electrically connected between an input of the inverting amplification block and an output of the inverting amplification block, and a switchable capacitor is electrically connected between the input of the inverting amplification block and the control pad. The control pad can be electrically connected to a DC voltage source or to the output pad to control the amplifier's closed-loop bandwidth.
