An improved I/V converter for analogue neural network applications is presented, using devices operating in the subthreshold mode of conduction. The proposed scheme employs diode connected transistors biased by a network incorporating feedback. Analysis and simulation suggest that the modified structure offers a substantial reduction in the sensitivity to supply voltage variations. As the proposed scheme uses only NMOS transistors, it can be implemented in a standard single well process.
