20220263469 | TURN ON TIME ACCELERATION OF A CASCODE AMPLIFIER - Various methods and circuital arrangements for reducing a turn ON time of a cascode amplifier are presented. According to one aspect, a configurable switching arrangement coupled to a cascode transistor of the amplifier shorts a gate of the cascode transistor to a reference ground during an inactive mode of operation of the amplifier. During an active mode of operation of the amplifier, the configurable switching arrangement couples a gate capacitor to the gate of the cascode transistor that is pre-charged to a voltage that is higher than a gate biasing voltage to the cascode transistor, which ensures that cascode transistor turns ON much quicker than the traditional method of grounding the cap, hence provide a final current flow through the cascode amplifier in a shorter time by not limiting the turn ON time of the input transistor. The gate biasing voltage is coupled to the gate capacitor via a resistor. A relationship between the pre-charged voltage, and minimum saturation voltages and threshold voltages of the transistors of the cascode amplifier is also provided. | 2022-08-18 |
