One of the principal economic drivers for the semiconductor industry is high performance, low power applications for the portable electronics consumer market. Unfortunately, the power dissipation resulting from the use of conventional CMOS technology in this area is becoming a critical design issue. Supply voltage reduction has been the preferred technique for reducing power dissipation. Howeve...

A low-voltage and low-power voltage mode adder/subtractor using MOSFETs in weakinversion is presented in this paper. Since the MOSFETs in the proposed circuit are biased in weak inversion, consequently its power dissipation is very low. The proposed circuit has been simulated with the HSPICE using a N-well 0.35μm 2p4m process and the results show that, under the supply voltage of 1V, the power ...

In the high performance integrated circuits phenomena like crosstalk, IR drops, electromigration and ground bounce are assuming increasing proportions because of the growing complexity in ultra deep submicron designs: their consequences are assuming increasing dimensions compromising circuits functionality and not only their performances. This paper suggests a methodology to evaluate and to pre...

The self-oscillating flyback converter is a popular circuit for cost-sensitive applications due to its simplicity and low component count. It is widely employed in mobile phone chargers and as the stand-by power source in off-line power supplies for data-processing equipment. However, the optimization of this circuit is almost exclusively performed by a cutand-try approach since its operation i...

Clock distribution networks consume a major portion of the power of a chip . Continuous Scaling of VLSI Technology i.e Channel length ,Supply has lead to integration of millions of transistors on a single chip operating at very high clock frequencies. Besides area and performance, the modern VLSI designs aim at low-power consumption due to limited battery lifetime. Most voltage scaling techniqu...

Energy consumption of digital circuits has become a primary constraint in electronic design. The increasing popularity of the portable devices like smart phone, ipad, tablet and notebook has created an overwhelming demand for extended battery life of these devices. Numerous methods for energy reduction in CMOS circuits have been proposed in the literature. Power reduction techniques at various ...

In this paper, the effect of the cell-temperature on the performance of photovoltaic (PV) module is evaluated. The evaluation is based on a mathematical module (single diode equivalent circuit) and practically based on solar module tester (SMT). Solara®130W PV crystalline silicon module was used in this simulation. The SMT is able to supply a constant irradiance level (1000W/m2) or any other de...

A low-power field-programmable VLSI (FPVLSI) is presented to overcome the problem of large power consumption in fieldprogrammable gate arrays (FPGAs). To reduce power consumption in routing networks, the FPVLSI consists of cells that are based on a bit-serial pipeline architecture which reduces routing block complexity. Moreover, a level-converter-less multiple-supply-voltage scheme using dynam...

This paper analyzes maximum output power of class E amplifier with arbitrary transistor. It is important to estimate maximum output power of class E amplifier when a specification of transistor is given. In this paper, values of circuit parameters that gives maximum output power for given operating frequency, dc supply voltage, and output capacitance of the transistor are calculated. This paper...
