摘要：
A bandgap reference circuit employing subthreshold current is proposed. Only a small fraction Of V(BE) is utilized to generate the reference voltage of 170mV. Since the subthreshold current of MOSFET's is used as the current source, the circuit only consumes 2.4 mu W at supply voltage of M It was fabricated using 0.18 mu m CMOS triple-well. technology on chip area of 0.029mm(2). Both of the measurement and the simulation demonstrate the reference voltage variation is 1.3mV from -20 degrees C to 100 degrees C and is 1.1mV per volt for supply voltage from 0.95V to 2.5V.
