TLDR
In this paper, a switch configuration to be used at the input of switched op amp circuits is introduced, which is an extension of the gate-source bootstrapping technique such that rail-to-rail operation of the input switch becomes possible.Abstract:
A switch configuration to be used at the input of switched op amp circuits is introduced. The circuit is an extension of the gate-source bootstrapping technique such that rail-to-rail operation of the input switch becomes possible. Simulations show the usefulness of the proposed circuit down to 0.9 V.read more
