“Safety margin” for a logic circuit introduces a performance overhead. But eliminating safety margin makes a system more prone to timing failure, particularly under dynamic operating variations. This paper presents dynamic timing control technique that allows a system to operate without any safety margin. The dynamic control method prevents timing errors utilizing time borrowing and elastic clocking...
In this paper, a dynamic timing control technique employing a time-borrowing flip-flop with a time-borrowing detection and a clock shifter is presented to prevent timing errors of a system with a minimized performance penalty. The proposed flip-flop allows time borrowing during a time-borrowing window (TBW) on critical paths and generates a time-borrowing detection signal used by the clock shifter...
A low-power multiresolution spectrum-sensing (LP-MRSS) IC utilizing self-deactivated partial swing techniques is fabricated in 0.18-??m complementary metal-oxide-CMOS technology. The LP-MRSS is composed of a low-power digital window generator, analog correlators, low-power pipeline analog-to-digital converters, and a fast-sweeping frequency synthesizer. The LP-MRSS dissipates 122 mW at a 1.8-V supply...
