The Design of a Bootstrapped Sampling Circuit [The Analog Mind]
Behzad Razavi
Abstract
Bootstrapped samplers serve as an integral component of analog-to-digital converters (ADCs). The bootstrapping action reduces the distortion and improves the speed with a minimal power penalty. In this article, we present the step-by-step design of this circuit to see how the analog mind goes about such a task. The reader is encouraged to review the sampler's detailed operation [1]-[4] before continuing with this article.
