Abstract
A startup circuit includes a first circuit leg coupled between an input node and an output node and a second circuit leg coupled between the input node and the output node. The first circuit generates a first current and the second circuit leg sinks current from a first node based upon the first current. A third circuit leg is coupled between the input node and the output node and sources current to a second node based upon a voltage at the first node to thereby generate a feedback voltage at the second node. The first circuit leg increases the first current based upon the feedback voltage, in turn increasing the current sunk from the first node by the second circuit leg and increasing the current sourced to the second node by the third circuit leg to thereby generate a startup current at the output node.
