A New No Op Amp Full CMOS Voltage Reference Circuit

Abstract:

A no op amp structure full CMOS reference voltage circuit is designed. The two currents which are proportional to absolute temperature (PTAT) and complementary to absolute temperature (CTAT) are added together to get the reference output voltage which is obtained through a resistance. The characteristics of the new circuit are simulated using 0.5 μm BSIM3V3 spice models in HSPICE. The simulation results show that the output voltage of the circuit is 997mV, the power consumption is 1.12mW, the temperature coefficient is 15.2 ppm/°C in the range from-30°C to 100°C at the supply voltage of 2V.
