Abstract

This paper presents a CMOS band-gap reference design, which possesses the characteristics of low noise and high power supply rejection capability. Thus, it is suitable for the applications of a wide range of frequency and power input. In order to reduce thermal noise and to provide the output reference voltage that is resistant to power supply variations, the design incorporates an RC filter into conventional reference structure. Moreover, a fast turn-on circuit is introduced into the design to improve turn-on time of the circuit. The simulation results show that within the frequency range from 100Hz to 10MHz, the design has achieved an average power supply rejection ratio (PSRR) of more than 80dB and an average noise of 8.5uVrms. With the fast turn-on circuit, the improved band-gap reference circuit can reach its steady state within 100 microseconds.
