Abstract:
An integrated circuit includes a plurality of analog inputs, and an analog multiplexer (MUX). The MUX includes a common output node configured to provide a MUX output, a plurality of analog switches, and a shared buffer. Each switch includes a corresponding bootstrap circuit coupled to a control electrode of a corresponding pass transistor in which the corresponding bootstrap circuit includes a corresponding boosting capacitor. Each analog switch of the plurality of analog switches has a first input coupled to a corresponding analog input of the plurality of analog inputs, a second input, and an output coupled to the common output node. The shared buffer has an input coupled to the common output node and coupled to provide a common buffered MUX output to the second input of each of the plurality of analog switches.
