ANALOG CIRCUITS HAVING IMPROVED TRANSISTORS, AND METHODS THEREFOR

摘要

Circuits are disclosed that may include a plurality of transistors having controllable current paths coupled between at least a first and second node, the transistors configured to generate an analog electrical output signal in response to an analog input value; wherein at least one of the transistors has a deeply depleted channel formed below its gate that includes a substantially undoped channel region formed over a relatively highly doped screen layer formed over a doped body region.

1. A circuit, comprising:
a plurality of transistors having controllable current paths coupled between at least a first node and a second node, the transistors configured to generate an analog electrical output signal in response to an analog input value; wherein at least one of the transistors operates with an applied body bias, and has a deeply depleted channel formed below its gate that includes a substantially undoped channel region formed over a doped screen layer formed over a doped body region, with the doped screen layer extending between and in contact with a source and a drain.
