Abstract
One or more techniques and systems for starting an output driver and an associated start-up circuit are provided herein. In some embodiments, a voltage provider is configured to charge a charge store to a pre-turn-on voltage. In some embodiments, an output driver is configured to control a connection between the charge store and the output driver. For example, the connection enables the charge store to discharge a voltage to the output driver, thus starting the output driver. Accordingly, a response time associated with starting the output driver is mitigated at least because the charge store is charged to the pre-turn-on voltage and connected to the output driver such that a gate of the driver is biased in a sudden fashion. In this manner, the driver is turned on more quickly. Additionally, effects associated with process, voltage, and temperature variations are mitigated, for example.
