Abstract
A low power voltage reference circuit with all MOSFET structure was presented based on the different current characteristics of the MOSFET sub-threshold region, linear region and saturated region. The MOSFET working in linear region was designed to replace the ordinary resistance, to realize the all MOSFET characteristic, at the same time, the circuit layout area was effectively reduced. Besides, the output reference voltage was used as the bias of the MOSFET to further reduce power consumption. The circuit was designed with SMIC 0.18μm CMOStechnology. Results denote that the temperature coefficient is 22.6×10–6/℃ in –50-+150℃ with the power supply of 1.8 V, and the output voltage of the voltage reference circuit is 992 mV. The static current at 25℃ is 327.3 nA, and the power consumption is 0.59μW. Besides, the power supply rejection ratio is –25.36 dB at 10 kHz.关键词
