Abstract
An integrated circuit amplifier includes, in an exemplary embodiment, a first field effect transistor (FET) device configured as a common source amplifier with source degeneration and a second FET device configured as a tunneling gate FET, the tunneling gate FET coupled to the source follower. The tunneling gate FET is further configured so as to set a transconductance of the amplifier and the common source amplifier with source degeneration is configured so as to set an output conductance of the amplifier.
