Abstract

A device comprises a voltage-mode filter circuit, a current-mode output circuit, and a regulation circuit. The voltage-mode filter circuit is configured to generate a voltage signal on an output terminal thereof. The current-mode output circuit comprises an input transistor which comprises a gate terminal coupled to the output terminal of the voltage-mode filter circuit, and a source terminal coupled to a regulated node. The regulation circuit is configured to adjust a voltage level on the regulated node to maintain a constant gate-source bias voltage for the input transistor to generate a current for biasing the current-mode output circuit.
