Abstract
An IIL circuit includes a current mirror circuit that receives a constant current as an incoming signal and which inverts and amplifies the constant current to produce an outgoing inverted current. The current mirror circuit adds the incoming constant current to the inverted current and supplies the sum of those currents as an injector current to the respective injectors of a plurality of IIL gates.
