Design of the modified energy recovery logic circuit

The power consumption of the ECRL is analyzed in this paper. To overcome the shortcomings of the ECRL circuit, the modified energy recovery logic (MERL) is proposed. By increasing the additional energy recovery path, the MERL structure can completely recovered the energy on the output nodes. The characteristics of the MERL are simulated using 0.5um BSIM3V3 spice models in HSPICE. The simulation results show that the MERL circuit has much lower power consumption compared with the traditional CMOS logic. The energy can be completely recovered in the recovery phase in the MERL inventor, and the power dissipation of MERL will be lower than the ECRL when load capacitance is increased.
