DTCMOS differential amplifier

摘要

An amplifier is constructed having a FET formed in a substrate with its gate coupled to a first voltage terminal. A second FET formed in the substrate is coupled both to the first FET and to a second voltage terminal. The second FET has its gate directly coupled to its body. The second FET electrically isolated from the substrate. An input node at the coupled gate-body receives an input signal. An output node between the first and second FETs outputs a signal in response to the input signal.
