An Attempt Towards Charge-Domain Logic (CDL)

Abstract

Application examples of charge-domain logic are described. To investigate the characteristics and possibilities of charge-domain logic, prototype implementations are made for full adder and CRC checker designs by standard CMOS, and fabricated by MOSIS 1.5u, double overlapping poly, and double metal technology. Those application designs require less than 8 steps of charge transfer so that no special fabrication process is required. Some of the results from evaluation experiment for both designs are also included.
