Abstract
An amplitude detection circuit using a sinusoidal input signal inputs to produce a digital output (a one or zero) is described. The circuit uses an input field effect transistor (FET) with a gate load coupled to a gate of the input FET. A drain load may be coupled to a drain of the input FET. A source load may be coupled to a source of the input FET. A controllable variable current generator provides a current to the source of the input FET, biasing the source of the input FET to a reference voltage. An input signal conductor may be coupled to the gate of the input FET. Other embodiments are described.
