21st International Conference on VLSI Design (VLSI Design 2008)
A 9 bit 400 MHz CMOS Double-Sampled Sample-and-Hold Amplifier
Hyderabad, India
January 04-January 08
ISBN: 0-7695-3083-4
fier(SHA) is described here.The circuit is designed as a front end sampler of a low-power,high-speed analog to digital converter.The SHA uses double-sampling technique to achieve high speed with reasonably low power consumption.Using 0 .18? CMOS technology,a resolution of 9 bit has been achieved at a sampling rate of 400MHz.Also,to acquire superior linearity, boot-strapping technique has been used while implementing the switches and to reduce clock feed through, concept of bottom plate sampling has been utilized.Using a supply voltage of 1.8 V and a signal swing of 0 .6Vpp the circuit consumes approximately 10 mW of power.
