Abstract
The disclosed amplifier includes first and second gain stages and first and second frequency compensating capacitors. The second gain stage has a first high impedance node coupled to the first gain stage, a second high impedance node, a first circuit coupled between the first and second high impedance nodes, a third high impedance node, and a second circuit coupled between the second and third high impedance nodes. The impedances at the first, second and third high impedance nodes are a function of frequency and the impedance at the second high impedance node is lower at any given frequency than the impedances at the first and third high impedance nodes. The first frequency compensating capacitor is coupled between the first and third nodes and the second frequency compensating capacitor is coupled between the third and second nodes.
