To produce sub 1 V bandgap reference voltage in pipelined analog to digital converter (ADC) and decrease power dissipation of reference circuit, a novel differential voltage reference was presented. Based on traditional bandgap reference, resistors were added to base and emitter of transistor, so that the bandgap voltage could be adjusted according to the proportionality coefficient of resistors. To simplify the amplifier of the reference circuit, a single-ended to differential converter based on current-mode circuit was adopted. The circuit was implemented and simulated in TSMC 0.18 μm CMOS process. Experimental results showed that VREFP and VREFN was 1.156 V and 0.656 V respectively at 25 ℃. In the temperature range of -40 ℃~125 ℃, the variances of the reference voltages and the value of temperature coefficient were less than 6 mV and 4.6×10-5/℃ respectively. The PSRR of the reference circuit was 115 dB at low frequencies. A pipelined ADC for high-resolution video signal processing using this reference circuit achieved a resolution of 10 bit and a sampling rate of 170 MS/s.
