In this work a low power, low voltage and high gain operational amplifier is proposed. For this purpose a negative resistance structure is used in parallel with output to improve the achievable gain. Because of using self cascode transistors in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain. To evaluate the...

This work describes the design of a divder technique Low-power techniques are applied in the design of the unit, and energy-delay tradeoffs considered. The energy dissipation in the divider can be reduced by up to 70% with respect to a standard implementation not optimized for energy, without penalizing the latency. In this dividing technique we compare the radix-8 divider is compared with one ...

Emerging Wireless Body Area Networks (WBANs) are receiving increasing interest from researchers and designers. Specific requirements for small-scale dimensions, low-latency, lightweight and limited power capacity mean that the key challenge in WBANs design is in the adoption of energy-efficient strategies for better system performance, and in the efficient use of high data-rate and ultra-low-po...

This paper mainly focused on implementation of AES encryption and decryption standard AES-128. All the transformations of both Encryption and Decryption are simulated using an iterativedesign approach in order to minimize the hardware consumption. This method can make it avery low-complex architecture, especially in saving the hardware resource in implementing theAES InverseSub Bytes module and...
