Design and Evaluation of Power Efficient Shift Register Featuring Low Power Automatic Manufacturing Systems

Abstract

Microcontrollers are the noteworthy elements for controller unit of automatic manufacturing systems and industrial instrumentation devices. As well the advantages of fast production, low cost and time saving, on the other hand the automatic manufacturing systems with less utilization of power is being expected. The shift registers are the key component of microcontroller and one of the major power consuming components. The power efficient design of shift register makes the microcontroller with less power consumption.  The design of power efficient shift register will result significant impact on the total power utilization of automatic manufacturing systems. In this work 4-bit power efficient parallel to serial data converter is proposed by using clock tree shared twin nail activating flip-flop as elementary building block. The proposed shift register is implemented in DSCH &MICROWIND EDA tool and the enactment of suggested design is investigated by simulating it at 0.12mm CMOS process technology. The simulation upshots that, the proposed design consumes the power of 35.138 ?w and area occupation of 1554 ?m2.
