The sense amplifier incorporates a writing circuit for MRAM bits switched magnetic tunnel junction (MTJ). By combining read and write functions in a single power-efficient circuit, the PWSA allows for fast read and write operations while minimizing the bit error rate (BER) after data programming. Using the pre-read and comparison steps in the data program operation, we are able to reduce write power consumption under random data input conditions. By using the voltage controlled magnetic anisotropy (VCMA) effect for precessional switching, more than 10x reduction of write power and transistor size both in the memory cell and the write circuit is achieved, compared to using the spin transfer torque (STT) effect by the modified differential amplifier with XOR and XNOR gates. In this paper achieved less area, reducing the power and modified circuit for xno...

Using the Internet of Things, medical data can be collected and transmitted automatically to doctors through the Bluetooth module and Wi-Fi network from anywhere around the world and feedback can be returned to the patients. In this research project, we developed an Internet of things based health care system for patients with mobile apps and web browsers. Specially, we aim to address the issues regarding the usefulness of the ECG data collected from patients themselves. Algorithms for ECG enhancement, ECG quality evaluation and ECG parameters extraction were implemented in the system. The system was demonstrated by a use case, in which ECG waveforms are uploaded to the Personal computer and Heart beat count, along with body temperature and acceleration parameters are uploaded to the mobile app using Bluetooth module and web browse...

Reversible logic design has been one of the promising technologies gaining greater interest due to less dissipation of heat and low power consumption. ALU is a fundamental building block of a central processing unit (CPU) in any computing system; reversible arithmetic unit has a high power optimization on the offer. By using suitable control logic to one of the input variables of parallel adder, various arithmetic operations can be realized. In this paper, ALU based on a Reversible low power control unit for arithmetic & logic operations is proposed. In our design, the full Adders are realized using synthesizable, low quantum cost, low garbage output Double Peres (Dperes or DPG)Gates. This paper presents a novel design of Arithmetic & Logical Unit using Reversible control unit. These Reversible ALU has been modeled and verified using Verilog and Xilinx ISE simulator. Compa...
