Abstract
A transimpedance amplifier circuit with an AC signal path and a DC bias path separate from the AC signal path that may be used with a wide variety of sensors such as MEMS accelerometers, photo detectors and pressure sensors. The circuit includes a high impedance input pseudo-resistor that minimizes the area needed on an integrated circuit and configured to minimize losses, noise injection, noise gain and distortion while maintaining amplifier bandwidth, linearity and output voltage range.
