Patent ID: 11953970

Abstract:
A controllable voltage source (902) is coupled to a microelectronic circuit (901) for providing an operating voltage. Said microelectronic circuit (901) is adaptive, so its performance is at least partly configurable by value of said operating voltage. The operating voltage is regulated into conformity with a target value. Reregulating said operating voltage into conformity with a new target value involves a time constant. On a processing path a first register circuit (502) comprises a data input coupled to an output of a preceding first logic unit (501). The microelectronic circuit (901) responds to a digital value at said data input changing later than an allowable time limit by generating a timing event observation (TEO) signal. The allowable time limit is defined by at least one triggering edge of at least one triggering signal coupled to the first register circuit (502). The system uses said TEO signal to trigger an increase in said operating voltage faster than said time constant.
