Configurable analog front ends for circuits with substantially gate enclosed inner electrode MOSFET switch

A configurable integrated circuit (IC), comprising:

• a substrate having a semiconductor surface that said IC is formed within and thereon, said IC including:
• 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,
• wherein said drain or said source is a Substantially Gate Enclosed (SGE) inner electrode relative to said gate stack and another of said source and said drain is outside said gate stack, and
• an analog bus,
• wherein said inner electrode of said first SGEFET is directly coupled to said analog bus, and
• a switch control that provides control signals to at least said gate of said first SGEFET for controlling a connectivity between said circuit module or said IO and said analog bus.
