Abstract
Examples are provided for a multi-stage track-and-hold circuit (THA). The multi-stage THA may include a first stage, a second stage, and a third stage. The first stage may be coupled to an input signal and configured to sample the input signal. The second stage may be coupled to the first stage and may include a buffer circuit. The third stage may be coupled to the second stage and can include a bootstrapped THA. The first stage may further include a shunted source-follower circuit and a switched source-follower circuit. The shunted source-follower circuit may include a first switch that can be operable to couple an output node of the shunted source-follower circuit to ground potential.
