Abstract
A high temperature photocurrent detector circuit including a transimpedance amplifier having multiple stages of gain, and a driver amplifier which generates a driver current that is proportional to the photocurrent flowing through a photocurrent sensor. The voltage source utilizes source voltage wires to generate a supply current that is proportional to the driver current enabling the photocurrent detector circuit to operate as a two wire photocurrent detector circuit.
