Abstract
An apparatus and method for implementing a bootstrapped switching circuit having improved (i.e. faster) turn-on time is provided. In an embodiment, an inner switching loop is implemented in a bootstrapped switching circuit where the inner switching loop is configured to turn on an input switch in the bootstrapped drive circuit independent of the drive circuit output. The embodiment decouples the inner switching loop circuitry from the output drive circuit of the bootstrapped switching circuit, which typically has a larger load capacitance than the inner switching loop. This allows the inner switching loop to turn on the input switch in the bootstrapped switching circuit faster and decreases the turn-on time of the bootstrapped switching circuit.
