Over the last 5 years some outstanding advances have been made in monolithic operational amplifiers. These devices have progressed from the point where they were an expensive curiosity, with marginal ...

The author describes the excellent performance of a Ka-band monolithic variable-gain amplifier monolithic microwave integrated circuit (VGA MMIC) using dual-gate AlGaAs-InGaAs pseudomorphic high ...

This letter reports a monolithic high-efficiency buck converter using all depletion-mode (d-mode) gallium nitride (GaN) HEMTs which integrates a dead-time generating driving circuit and a power stage.
