摘要：
This paper presents a voltage reference that utilizes the virtually diode connected MOS transistors biased in the weak inversion region The proposed architecture increases the gain of the feedback loop that consequently reduces the system sensitivity and hence improves the PSRR The circuit is designed and simulated in a standard 0 18 mu m CMOS technology The simulation results in HSPICE indicate the successful operation of the circuit as follows the PSRR at DC frequency is 86 dB and for the temperature range from -55 degrees C to 125 degrees C the variation of the output reference voltage is less than 66 ppm/degrees C
