Adiabatic Switching and Charge Recycling are two new techniques to reduce power consumption: with the Adiabatic Switching technique, heat dissipation on resistive device channels caused by dynamic charging and discharging is reduced if energy transfer period T >> RC, where RC is the time constant of the circuit. Exploiting the Charge Recycling technique, loss of stored energy in capacitive loads can be recovered for reuse in subsequent cycles. In this paper, we propose a new logic family - Pulsed Power Supply Cross-Coupled Differential Logic (PPS- CCDL), which integrates the adiabatic differential logic gate and a latch. PPS-CCDL can be shown througth derivations and simulations to dissipate less power than the previously proposed PPS-CMOS approach, by eliminating the PMOS trees and the unnecessary signal glitches and transitions in PPS-CMOS. A higher power saving of the overall system is anticipated since PPS-CCDL presents a smaller and data-independent capacitive loads to the pulsed power supply. We implemented an 8-bit pipelined adder with a 0.8um standard CMOS technology, which is under testing. Another application chip of PPS/static 23-bit correlator with 8-bit I/O was submitted to CIC for fabrication.
