Abstract :
This paper presents a new reference system with emphasis on low power design and high power supply rejection. The untrimmed reference provides a 600 mV output voltage, which only differs by 5.75mV in the temperature range between −40°C and +125°C and a PSRR of −157.2dB at 10Hz. The core part of the reference produces a reference potential of 416.1mV with a deviation of only 1.59 mV. Moreover, the circuit provides a 900mV output, a temperature independent 3 μA current and trimming possibilities for the temperature curves and the amplitude of output voltages and currents. Under all operating conditions, the post-layout Corner- and Monte-Carlo-Simulations show a power consumption of less than 40μA and ensure functionality across process, supply voltage and temperature variations.
