Abstract
A method and apparatus for regulating photocurrents is described. A photocurrent regulator may include a transistor having an associated cross-sectional area. The photocurrent regulator is coupled between an integrated circuit and a voltage source. When a dose rate event occurs within the integrated circuit, the photocurrent regulator, via the cross-sectional area, regulates a recombination path to the voltage source. Consequently, photocurrents within the integrated circuit are regulated, preventing permanent damage within the integrated circuit.
