CONFIGURABLE ANALOG FRONT ENDS FOR CIRCUITS WITH SUBSTANTIALLY GATE ENCLOSED INNER ELECTRODE MOSFET SWITCH

摘要

A configurable integrated circuit (IC) includes a substrate having a semiconductor surface that the IC is formed within and thereon. The IC includes a configurable Analog Front End (cAFE) including at least one circuit module or input/output (IO), an analog switch having at least a first substantially gate enclosed Metal Oxide Semiconductor Field Effect Transistor (SGEFET) having a gate stack including a gate on a gate dielectric, a source, and a drain. The drain or source is a substantially gate enclosed (SGE) inner electrode relative to the gate, and the other of the source and the drain is outside the gate. The inner electrode of the first SGEFET is directly coupled to an analog bus. A switch control provides control signals to at least the gate of the first SGEFET for controlling a connectivity between the circuit module and/or the IO and the analog bus.
