In high power CFET circuits, such as off-chip drivers, it is necessary to get the output of the circuit up to some minimum value as quickly as possible, and slowly bring the level to a higher value for the purpose of providing noise tolerance. This has been done in the past using two devices in parallel, an enhancement device and a depletion device. The enhancement device attains the initial value, and the depletion device provides the noise margin.
