Abstract
A precision gain AC coupled operational amplifier circuit utilizing an integrated resistor voltage divider network and switched capacitors is provided. Precise gain is obtained by the use of integrated capacitors, and a low frequency stabilizing pole in the order of 10 Hertz is created by proper selection of the ratio of the resistors in the divider network.
