dc.description.abstract The virtual ground reference buffer (VGRB) technique is introduced as a means to improve the performance of switched-capacitor circuits. The technique enhances the performance by improving the feedback factor of the op-amp without affecting the signal gain. The bootstrapping action of the level-shifting buffers relaxes key op-amp performance requirements including unity-gain bandwidth, noise, open-loop gain and offset compared with conventional circuits. This reduces the design complexity and the power consumption of op-amp based circuits. Based on this technique, a 12 b pipelined ADC is implemented in 65 nm CMOS that achieves 67.0 dB SNDR at 250 MS/s and consumes 49.7 mW of power from a 1.2 V power supply. en_US
