Abstract
A quick turn on apparatus and method for a NMOSFET switch are used to maintain the gate voltage of the NMOSFET switch non-zero but not enough to turn on the NMOSFET switch, such that the NMOSFET switch turns on more quickly when it is to be turned on. Seamless transition can be further achieved in a single pole double throw switching circuit by using the quick turn on apparatus and method.
