Abstract

A High performance sub-1V bandgap voltage reference (BGVR) with high power supply rejection ratio (PSRR) and low temperature coefficient (TC) is proposed in this paper. An improved PSRR scheme is inserted to isolate the supply voltage of the error amplifier and the supply voltage of BGVR core from a power supply source in order to achieve a high PSRR. The proposed circuit is designed and simulated in 0.18μm CMOS 1.8V/3.3V technology. The proposed BGVR deliver an output voltage of 0.6346V at 27°C and the measurement temperature coefficient is 22,3ppm/°C over temperature range -40°C to 140°C, the DC value of PSRR is -93dB at 10kHz and -71dB of PSRR is achieved at 1MHz and a line regulation of 104μV/V is achieve over supply voltage range 1.2V to 1.8V. The area of layout is 0.0337 mm2. The proposed sub-1V bandgap voltage reference is suitable for low power LDO regulators and switching regulators.
