Abstract:
The paper describes the design and the implementation of a track-and-hold (THA) amplifier suitable for a 14-b, 100 MS/s A/D converter, in 0.18 /spl mu/m CMOS technology. The THA is based on the flip-around architecture with telescopic cascode OTA. Adequate settling behavior was achieved by means of accurate analysis and design of the boosting amplifier with respect to its impact on the pole-zero placement. A modified bootstrap switch featuring a high linearity and reduced complexity is also presented.
