Abstract
The present invention enables efficient start-up of integrated circuit at low voltages. The present invention disconnects the output load from the circuit by placing the circuit connected to the output load into a high impedance state. Thus, the internal voltage of the circuit can be boosted before it is subject to drain from an external load. A comparator is connected to the circuit placed in the high impedance state and determines when the internal voltage has reached a sufficient level so that the effect of the external load on the efficient operation of the circuit will be minimized.
