Abstract: |
Characters of the invention are as following: besides structure of sensitive amplifier is adopted in latch in first stage, pull-up and pull-down are carried out for two complemental output ends by using two pieces of P tubes and two pieces of N tubes at power source end and complemental output ends respectively. Control signals pulled-up and pulled-down are set and reset signals. Two pieces of phase latches in single clock with identical circuit parameter are adopted in latch in second stage. Potential retention unit structured from two inverters connected at headers is added between output ends of two pieces of phase latches. Comparing prior art, the invention saves energy 20% under same testing condition. Moreover, the invention possesses features of simple structure, small area of circuit, good characteristics of circuit time delay, setup time and metastable state time. |
