Abstract

The targeted 16 bit pipeline converter has an adjustable sampling frequency from 100MHz to 200MHz. In this paper the switches for the input and the reference voltage sampling are analyzed. Therefore, a novel switch bootstrapping technique is presented, which guarantees a worst case input voltage settling accuracy of LSB 2 at settling times between 2 ns to 5 ns. The non-linearity caused by the input switches is simulated and typically amounts to -115 dB. In addition a possible solution for external reference voltage settling is introduced.
