Abstract
An exemplary circuit embodiment includes a depletion-mode transistor and an enhancement-mode transistor. The circuit also includes a circuit portion coupled to a gate region of the depletion-mode transistor and to a gate region of the enhancement-mode transistor. In this embodiment, the circuit portion is configured to provide a reference voltage at an output node, wherein the reference voltage is associated with a difference between a voltage at the gate region of the depletion-mode transistor and a voltage at the gate region of the enhancement-mode transistor.
