IMPROVED STRUCTURE FOR EFFICIENT CHARGE RECOVERY LOGIC

An improved structure for efficient charge recovery logic (IECRL) with better power performance than ECRL coupled with an improved output wa veform is presented. At 25MHz and V-dd = 5V, the power dissipation of IECRL is similar to 60% that of the ECRL circuit. HSPICE simulations a lso show that the voltage can be scaled down to 1.5V V-dd and that the power saving is further improved. At 25MHz and V-dd= 1.5V, the power dissipation of the IECRL circuit is similar to 49% that of the ECRL, c ircuit.
