The voltage and current bandgap reference are widely used in analog circuit to supply either a constant bandga preference or a constant current reference. The proposed chip, which is designed with TSMC 0.35μm 2P4M CMOS process, can simultaneously provide a temperature-independent bandgap reference and a temperature-independent current reference. According to the simulation results, the constant voltage of bandgap reference, constant current of bandgap reference, voltage temperature coefficient, current temperature coefficient, power dissipation and minimum supply voltage are 888.6 mV, 736 nA, 39 ppm/℃, 120 ppm/℃, 91.28 μW and 1.35 V, respectively.
