Short-range wireless technologies can transmit real-time voice, audio, picture, and video communications. Such networks’ energy usage transmission reach are crucial, especially for portable power autonomous devices. Voice over Zigbee technology’s goal is to create a competitive service that excels in these performance factors. IEEE standard 802.15.4 specifies two layers low-rate WPANs: the phys...

For large high-speed globally synchronous ASICs, designing the clock distribution net becomes a troublesome task. Besides problems caused by clock skew, the clock net also is a major source of power consumption. Partitioning the design into locally clocked blocks reduces clock skew problems and if handled correctly it also reduces power consumption. However, to achieve these positive effects, t...

An operational amplifier is one of the key functional blocks and is widely used in analog and mixed-signal circuits. For lowpower consumption, many techniques such as class AB and slew-rate enhancement have been proposed. Although phase compensation is related to power consumption, it has not been clearly discussed from the viewpoint of the power consumption. In this paper, the conventional and...

This paper describes a CMOS analogy voltage supper buffer designed to have extremely low static current Consumption as well as high current drive capability. A new technique is used to reduce the leakage power of class-AB CMOS buffer circuits without affecting dynamic power dissipation. The name of applied technique is TRANSISTOR GATING TECHNIQUE, which gives the high speed buffer with the redu...

Two new low-power, and high-performance 1bit Full Adder cells are proposed in this paper. These cells are based on low-power XOR/XNOR circuit and Majority-not gate. Majority-not gate, which produces Cout (Output Carry), is implemented with an efficient method, using input capacitors and a static CMOS inverter. This kind of implementation benefits from low power consumption, a high degree of reg...

abstract introduction: nowadays, the advanced technology of designing electronic circuits in very small size and with very low power consumption has led to development of wearable and implantable medical devices. however, the electronic circuits need power supply that is usually provided by relatively large and heavy batteries. the discharged batteries have to replaced or recharged for long tim...
