Abstract:

A novel scheme for a CMOS low-voltage reference is proposed. It uses current subtraction between the currents generated by two instances of the same current generator circuit, each one configured with different magnitude and temperature coefficients. Temperature stability is achieved owing to the partial compensation of the MOSFET threshold voltage and mobility temperature effects. For a nominal reference voltage of 436.5 mV, SPICE simulation reveals a ±38.2 ppm/°C temperature coefficient within the range of -20 °C to 100°C.
