Abstract

This paper presents a novel low voltage reference circuit under the MOS threshold voltage(V$_{th}$) in standard CMOS process. It is based on the weighted difference of the gate-source voltages of an NMOS and a PMOS operating in saturation region. The voltage reference is designed for low power OLED driver ICs. The proposed circuit is designed using 0.35${\mu}{\textrm}{m}$ CMOS technology. The minimum supply voltage is 2V, and the typical temperature coefficient is 99.6ppm/ C.C.
