Abstract
This paper describes a CMOS voltage reference that makes use of weak inversion CMOS transistors and linear resistors, without the need for bipolar transistors. Its operation is analogous to the bandgap reference voltage, but the reference voltage is based on the threshold voltage of an nMOS transistor. The circuit implemented using 0.35μm n-well CMOS TSMC process generates a reference of 741mV under just 390nW for a power supply of only 950mV. The circuit presented a variation of 39ppm/°C (after individual resistor trimming) for the −20 to +80°C temperature range, and produced a line regulation of 25mV/V for a power supply of up to 3V.
