Abstract
A new 1 V supply voltage reference, using a standard CMOS process, with threshold voltage close to the supply voltage is proposed. The threshold voltages of NMOS and PMOS are 0.81 V and -1.05 V respectively at a temperature of -25°C. Simulation results show that the proposed design can achieve below 4.3 ppm/°C between -25°C and 150°C at supply voltage of 1 V; as the supply voltage increases to 2 V, the temperature coefficient only increases to 9.3 ppm/°C.
