Comparison of Power Efficient Inverter Circuit using adiabatic technique

Abstract

The power decadence in conventional CMOS (Complementary Metal oxide Semiconductor) circuit can be diminished by utilizing adiabatic method. Working of Adiabatic logic depends on switching activities, which diminishes the power by giving energy dissipated as heat back to supply. Adiabatic word has come from thermodynamic framework which says that no heat transfer take place from framework to climate as well as the other way around. Adiabatic logic is well known as energy recovery logic because its main objective is to reuse energy. It reuses the energy back to the power supply along the lines diminishing the power dissipation. Adiabatic procedures depend on adiabatic logic guideline. Anu Priya has propose the technique in 2014 [3], of adiabatic procedure where energy dissipation in PMOS organization can be limited and some of energy dissipated at load capacitance can be reused rather than dispersed as heat. Yet, the adiabatic method is exceptionally reliant upon parameter variation. Expecting completely adiabatic activity from a circuit is practically not possible as it is an ideal condition, also adiabatic technology is highly dependent on parameter variations so it’s quite difficult to achieve and ideal adiabatic circuit. It could be just accomplished with extremely sluggish exchanging speed. In examination, three logic families, ECRL (Efficient Charge Recovery Logic), PFAL (Positive Feedback Adiabatic Logic) and CPAL (Complementary Pass Transistor Adiabatic Logic) are contrasted and conventional CMOS logic for inverter circuit. MICROWIND technology is used while investigating different adiabatic circuits; energy utilization is broke down by variety of parameter. Result shows that adiabatic strategy is better decision in case of underpowered application in explicit frequency range.
