Abstract
Circuits, systems, and methods for starting up analog devices are provided. One circuit includes an output node at an output voltage (VOUT), a comparator configured to be coupled to a reference voltage (VREF), a feedback loop coupling the output node to the comparator, and a turbo circuit coupled between the output and the output node. The turbo circuit is configured to increase VOUT, the comparator is configured to compare VOUT and VREF, and the turbo circuit is enabled and disabled based on the comparison of VOUT and VREF. One system includes an analog device coupled to the above circuit. A method includes enabling the startup portion to start up the driver portion when VOUT is outside a predetermined voltage of VREF, disabling the startup portion when VOUT is within the predetermined voltage, and enabling the driver portion to drive the analog device subsequent to disabling the startup portion.
