Abstract
Adiabatic circuits are introduced for ultra-low-power applications. This work presents the impact of the power net on the ideal trapezoidal power supply waveform. An oscillator consisting of four 90-degree shifter is simulated in a 0.13mgrm CMOS technology providing a conversion efficiency of 85%. The trapezoidal waveform is distorted after a long line because harmonics are inhibited and the signal is delayed. A disturbed phase relationship does not affect energy dissipation and a phase margin larger than 30 degrees is provided. For high frequencies the impact of phase delay on the energy dissipation can be neglected.
