A New CMOS Current Reference with High Order Temperature Compensation
A new high order CMOS temperature compensated current reference is proposed in this paper, which is accomplished by two first order temperature compensation current references. The novel circuit exploits the temperature characteristics of integrated-circuit resistors and gate-source voltage of MOS transistors working in weak inversion. The proposed circuit, designed with a 0.6 μm standard CMOS technology, gives a good temperature coefficient of 31ppm/℃ -50~100 ℃ at a 1.8 V supply, and also achieves line regulation of 0.01%/V and .120dB PSR at 1 MHz. Comparing with other presented work, the proposed circuit shows better temperature coefficient and Line regulation.
