ABSTRACT:
A reference circuit can include a reference section that provides a reference value for other circuits of an integrated circuit and can be enabled and disabled in response to an enable signal. The reference circuit can include at least a first node, draw a reference current in the enabled mode, and draw essentially no current in the disabled mode. A pulse start-up section can provides a low impedance path between the first node and a first potential for a predetermined duration in response to the reference circuit being enabled. A continuous start-up section can provide a low impedance path between the first node and the first potential based on a logic state of an enable signal.
