Abstract :
A novel bandgap reference based on CMOS technology is presented in this paper. The main feature of the circuit is the wide input voltage range. It consists of two stages based on voltage-connection, for the first stage an improved structure is adopted to provide the relative high output voltage and for the second stage an amplifier is used to ensure the high accuracy. The circuit is simulated with HSPICE using SMIC 0.35 mum mixed signal models, and the results show that it possesses a temperature coefficient(TC) of 3.82times10-6 K-1 with temperature range from -40degC to 85degC. Under a wide input voltage range from 5 V to 36 V, it possesses the power supply rejected characteristic of 0.209 mV/V and PSRR of 78 dB.
