Abstract
In this paper, a new design of adiabatic circuit, called the quasi-static efficient charge recovery logic (QSECRL) is proposed. To achieve minimum energy consumption, this paper proposes a technique to reduce channel resistance and remove diodes from the signal path. This design method can be implemented in both combination logic and sequential logic. The counter circuit and the 8-bit carry look-ahead (CLA) circuit, a more complex circuit, are selected to evaluate this proposed design. All simulations in this paper have been implemented by SPICE with the 0.8 μm MOSIS technology MOS transistor model under 2-volt (peak-peak) sinusoidal power-clock supply. The results show significantly improved performance of the 8-bit CLA circuit with 20-30 fJ and 70 fJ energy consumption at 10-100 MHz and 500 MHz operating frequency, respectively. © Birkhäuser Boston 2009.
