Smart IC Maintains Uniform Bias Current for GaAs MESFETs


Abstract:A current sensor that monitors the drain-source current (IDS) at the source of the MESFET and provides feedback to
the gate input overcoming the drawbacks of gate-turn-on threshold voltage variations for gallium-arsenide metal-semiconductor
field-effect transistors, GaAs MESFETs.

The gate-turn-on threshold voltage for gallium-arsenide metal-semiconductor field-effect transistors (GaAs MESFETs) varies
considerably from part to part, even within a given lot. That ……
