Abstract :
A low voltage low power voltage reference for biomedical and embedded applications is proposed. The reference voltage has been designed in a mixed-signal 0.13 mum CMOS process for source voltages as low as 0.5 V. The reference makes use of MOSFETs in the weak inversion region to consume nanowatts of power. Monte Carlo simulations show an average temperature coefficient of 2.2ppm/degC from -40 degC to 100 degC. The circuit layout occupies approximately 25mum times 10 mum and draws 80 nA from a 500 mV supply
