Abstract:
An amplifier comprising:an input differential amplifier (100) having a first input providing an inverting input (âˆ’) to the amplifier, and a second input providing a noninverting input (+) to the amplifier, and having an output forming a gain node; a compensation capacitor (106) having a first terminal coupled to the gain node and having an output coupled to a first power supply terminal; an output buffer amplifier (104) having an input coupled to the gain node and an output forming the output of the amplifier; and a correction amplifier (200) having a first input coupled to the output of the output buffer amplifier, a second input coupled to the gain node, and an output coupled to the gain node, wherein the correction amplifier comprises: a correction capacitor (304) having a first terminal coupled to the output of the output buffer amplifier, and a second terminal coupled to the gain node.
