摘要：
A Bandgap Voltage Reference (BGR) circuit technique for lower voltage supply operation is presented. It eliminates the need of BGR core and resistors by integrating a two-stage cascode operational amplifier (op-amp) biased with a start-up circuitry with all-MOSFET transistors. The circuit is designed in 0.13 mu m CMOS process technology, produced a 179mV reference voltage at 27 degrees C with 0.4V supply voltage. The simulated voltage reference achieved 0.02ppm/degrees C temperature coefficient over -60 degrees C to 45 degrees C temperature range as well as +/- 170mV over supply voltage variation from 0.1V to 1.2V. The design is simulated and verified with Mentor Graphics.
