摘要：In applied physics, an adiabatic process is defined as any process that is asymptotically isentropic(thermodynamically reversible), that is, whose total entropy generated tends towards zero in some appropriate limit(typically, of low speed and/or improved isolation of the system). As for example asymptotically reversible heatengines were first described by Carnot in 1825 [1], which shows maximum possible thermodynamic efficiency. Part ofthe cycle of Carnot‘s engines involved processes with no heat flow, and this lack was the original and literal meaning ofthe term ― Adiabatic ―. But today, we would call the entire Carnot cycle adiabatic, in the more general applied physicssense of term, which has departed from the literal meaning. The field of ― Adiabatic Circuits ―[2] applies the generalconcepts of adiabatics to the design of Low-power electronic circuits in particular, consisting primarily today of digitalMOSFET- based switching circuits[3].Demands for low power and low noise digital circuits have motivated VLSI designers to explore new approaches to thedesign of VLSI circuits. Energy recovering logic is a new promising approach, which has been originally developed forlow power digital circuits [4]. Adiabatic circuits achieve low energy dissipation by restricting current to flow acrossdevices with low voltage drop and by recycling the energy stored on their capacitors [1].Using this logic and its modification we have developed 7 segment display for digital combinational circuit design.
