Abstract:
1. A circuit comprising: a semiconductor switch adapted to switch between first and second states, wherein the first state is one of an off state or an on state, wherein the second state is an other one of the off state or the on state; a plurality of drive circuits coupled to the semiconductor switch, the plurality of drive circuits having a drive circuit impedance and coupled to provide a plurality of drive signals to switch the semiconductor switch from the first state to the second state; and a selector circuit coupled to the semiconductor switch through a connection to sense the semiconductor switch, the selector circuit further coupled to each of the plurality of drive circuits to select in response to the sensing of the semiconductor switch through the connection the drive circuits that provide the plurality of drive signals to the semiconductor switch to reduce the drive circuit impedance as the semiconductor switch switches from the first state to the second state.
