ABSTRACT:
Apparatus for efficiently supplying energy to a device in a circuit, the apparatus comprising a powered device having a critical path delay; delay line operative to model said critical path delay; control logic responsive to output from said delay line and operative to generate control output; and a power converter operative to adjust supply voltage to said powered device in response to said generated control output, wherein the delay line, the control logic, and the power converter cooperate to provide first order bang-bang control of said critical path delay.
