Abstract
Startup circuits with native transistors. In some embodiments, a startup circuit may include a first inverter configured to receive a bandgap voltage (V) from a bandgap reference circuit and to produce an output voltage (V), and a second inverter operably coupled to the first inverter to form a latch, the latch configured to maintain a value of V, the second inverter including a native transistor, the native transistor having a gate terminal coupled to Vand a source terminal coupled to V. In other embodiments, a method may include receiving Vat a startup circuit and outputting Vconfigured to change in response to Vrising above Vor falling below V, where the power consumption of the startup circuit is based at least in part upon a voltage value applied to a source terminal of a native transistor within the startup circuit.
