Abstract:
A gate pulsing gate ladder circuit includes a series connected resistor ladder with bond pads connected to the resistor ladder between adjacent resistors. An electrical node is positioned between a first and second resistor of the resistor ladder. The electrical node is electrically connected to a gate electrode of a field effect transistor (FET). A power supply produces a constant power voltage that is applied to a pre-selected bond pad to produce a desired bias voltage at the gate electrode of the FET. A selectable gate enable voltage source is connected to an and of the resistor ladder at the first resistor and is configured to produce a first and second voltage level that when combined with the constant power voltage produces a voltage level that causes the FET to be in a conducting state or non-conducting state, respectively.
