ABSTRACT:
Digital logic driving stage circuitry is provided connected between ground and a single voltage with an enhancement mode type field effect transistor and a depletion mode type field effect transistor connected source to drain in series between the single voltage and ground. The gate of the enhancement mode type field effect transistor is the input of the logic signal and the gate of the depletion mode type field effect transistor is connected to ground, with the output at the connection between the transistors. A family of digital logic circuits is provided with circuit units made up of an enhancement mode logic input, depletion mode load circuitry stage and an enhancement mode input grounded source follower load driving stage.
