Abstract
To overcome the limitation of the silicon energy gap in electron volts 1.2 V which leads to that the voltage reference is fixed at about 1.2 V, a design of current-mode (CM) architecture CMOS bandgap voltage reference with arbitrary voltage value by setting the resistor value is presented here with low 1.8-V power supply. The simulation results indicate a temperature coefficient (TC) of 5 ppm/°C from -20°C to 125°C after trimming and a power supply rejection ratio (PSRR) of 64 dB.
