Abstract :
A compact programmable CMOS voltage reference that is determined by the charge difference between two floating-gate transistors is introduced in this paper. A prototype circuit has been implemented in a 0.35μm CMOS process; reference voltages ranging from 50mV - 0.6V have been achieved and initial accuracy of ±40muV has been demonstrated as well. Experimental results indicate a temperature sensitivity of approximately 53μV/degC for a nominal reference voltage of 0.4V over a temperature range of -60°C to 140°C
