Abstract-An NMOS voltage reference has been developed that exhibits extremely IIOW drift with temperature. The reference is based on the difference between the gate/source voltages of enhancement and depletion-mode NMOS transistors. The theoretical depen&nce of the referenee voltage on both device and circuit parameters is analyzed and conditions for optimsf performance are derived. The reference NMOS transistors are biased to the optimizing current levelsby a unique feedback circuit. The measured output voltage ……
