Abstract

Abstract

A high performance CMOS sample and hold (S/H) circuit for use in the front end of a 12bit 100MS/s ADC is presented.It achieves a 108dB spurious-free dynamic range and 77dB signal-to-noise ratio over the Nyquist band at a 100MHz sampling frequency with a 3V power supply.An analysis model for the S/H circuit is built to capture the switching effect.The impact of the switches’ arrangement is also addressed.The leakage in a conventional bootstrapped switch is analyzed and some improvements are made,enhancing the linearity significantly.
- sample-and-hold circuit,
- bootstrapped switch,
- gain-boosting operational amplifier
