Abstract:
A system comprising:a well bias circuit including: an input; an output to provide bias to a charge well; a sensor including an output to provide a first signal associated with a first threshold condition; logic including: a first input coupled to said output of said sensor; a first output coupled to said input of said well bias circuit, said first output to provide a second signal to said input of said well bias circuit; wherein said logic is to assert said second signal if said first signal indicates that the first threshold condition has been exceeded; and an enable circuit including an output, said enable circuit to provide a third signal indicating said well bias circuit is enabled; wherein said logic further includes: a second input coupled to said output of said enable circuit; and wherein said logic is further to assert said second signal if said third signal indicates said well bias circuit is enabled.
