Abstract
A high-power solid-state RFPA includes an output stage having a power transistor and a current enhanced driver that drives the output stage. The current enhanced driver includes an inductor and first and second transistors arranged in totem-pole-like configuration. When the first transistor is turned on and the second transistor is turned off, the inductor supplies a first charging current to the output stage, to assist in charging the input gate-source capacitor (Cgs) of the power transistor in the output stage. The first transistor further provides a second charging current that supplements the first charging current, thereby enhancing charging of the gate-source capacitor Cgs. Conversely, when the first transistor of the driver is turned off and the second transistor is turned on, the second transistor provides a discharge path through which the gate-source capacitor Cgs can discharge.
