The manufacturing advances in semiconductor processing (continually reducing minimum feature size of transistors, increased complexity and ever increasing number of devices on a given IC) change the design challenges for circuit designers in CMOS technology. The important challenges are low power high speed computational devices. In this paper a novel low power adiabatic circuit topology is proposed. By removing the diode from the charging and discharging path, higher output amplitude is achieved and also the power dissipation of the diodes is eliminated. A mathematical expression has been developed to explain the energy dissipation in the proposed circuit. Performance of the proposed logic is analyzed and compared with CMOS and reported adiabatic logic styles. Also the layout of proposed inverter circuit has been drawn. Subsequently proposed topology-based various logic gates, combinational and sequential circuits and multiplier circuit are designed and simulated. The simulations were performed by VIRTUOSO SPECTRE simulator of Cadence in 0.18 μm UMC technology. In proposed inverter the energy efficiency has been improved to almost 60% up to 100 MHz in comparison to conventional CMOS circuits. The present research provides low power high speed results up to 100 MHz, and proposal has proven to be used in power aware high-performance VLSI circuitry.

This work is based on a new approach for minimizing energy consumption in quasi static energy recovery logic (QSERL) circuit which involves optimization by removing the non adiabatic losses completely. Energy recovering circuitry based on adiabatic principles is a promising technique leading towards lowpower high performance circuit design. The efficiency of such circuits may be increased by reducing the adiabatic and non-adiabatic losses

In this paper authors have presented a new approach to improve the performance of the glitch free cascadable adiabatic logic (GFCAL) circuit by replacing the triangular power supply with sinusoidal and trapezoidal power supplies (that control the charging and discharging of the capacitive load) and by sizing of transistors. A simulative investigation and performance analysis of proposed approach based 3 bit GFCAL counter, GFCAL JK flip flop and GFCAL 6T-SRAM circuit have also been done. The triangular power supply produces very large delay at the outputs of GFCAL circuits thus it will be very difficult to cascade larger circuits. A solution to provide cascadability is optimization of the delay. In the proposed approach the delay of GFCAL counter for triangular supply has been improved about 40% and 60% whereas for JK flip flop it is 46% and 49% and for 6T SRAM it is 17% and 91% with sinusoidal and trapezoidal power clocks respectively.
