Abstract
Apparatus and methods of controlling operating states of multi-stable electronic circuits are disclosed. In one aspect, an apparatus includes a bandgap reference circuit having an operating state and a latched off state. The bandgap reference circuit includes an amplifier to provide a bandgap reference voltage when the bandgap reference circuit is in the operating state. A state control circuit is also included and is coupled to sense an output signal of the bandgap reference circuit. The state control circuit is also coupled to provide a drive signal to an input of the amplifier in response to the sensed output signal. The drive signal is coupled to cause the bandgap reference circuit to avoid the latched off state.
