摘要：
A novel high-speed and high-precision voltage comparator has been proposed. In the comparator design, the Switched Operational Amplifier technique is adopted in the pre-amplifier stage to reduce the power consumption. The proposed voltage comparator is designed for 1MHz 12-bit SAR ADC under TSMC 180nm 1P6M CMOS technology. The resolution of the voltage comparator is 0.2mV under the 1.8V power supply with the sample rate of 20MS/s.
