Analysis of power-clocked CMOS with application to the design of energy-recovery circuits

This paper presents our research results on power-clocked CMOS design. First we provide algebraic expressions and describe the properties of clocked signals. Next two types of power-clocked CMOS circuit constructions are introduced and analyzed in detail. Since the adiabatic switching requires slow-ramping of the power-clock, a clocked transmission gate and a four-stage clocked NP-domino circuit are presented which receive trapezoidal and sinusoidal power-clocks, respectively. PSPICE simulations demonstrate the correct operation and energy-saving advantage of the proposed circuits.
