摘要
Abstract
We propose a voltage reference based on the weighted difference between the gate-source voltages of an nMOS and a pMOS operating in their saturation regions.No diodes or parasitic bipolar transistors are used.The circuit is simulated and fabricated with SMIC 0.18μm mixed-signal technology,and our measurements demonstrate that its temperature coefficient is 44ppm/℃ and its PSRR is -46dB.It works well when Vdd is above 650mV.The active area of the circuit is about 0.05mm2.关键词
