A bandgap reference with adjustable output voltage was designed based on TSMC 0.18 μm process and simulated by using Cadence software. Simulation results show that the temperature coefficient is 29×10–6/℃ in the range of –25 – +100℃, and the power supply rejection ratio PRSS is 63 dB at low frequencies. At 1.8 V supply voltage, the stable output voltage is 750 mV and the output voltage adjustment rang is about 20%, namely from 600 mV to 900 mV. Due to adjustable output voltage characteristic, the utility range of the reference is increased.
