Abstract
In this paper, a Combined CMOS Reference Circuit is proposed in UMC 180 nm standard CMOS Process. It consists of a start-up circuit, a current generator, and a voltage generator. This circuit achieves a nominal value of 50.11 μA and 776.4 mV for current and voltage respectively, from a 1.8 V supply voltage. The line sensitivity of 285 ppm/V and 347 ppm/V for current and voltage is achieved respectively, under the ±10 % variation in supply voltage. The temperature coefficient for current and voltage are 93 ppm/°C and 295 ppm/°C respectively in temperature ranges -40 °C to 125 °C.
