The first configuration can synthesize low-pass and high-pass filter functions according to the passive components used. The second one can synthesize a band-pass ...

The proposed circuit employs three differential difference current conveyors (DVCCs) as active elements together with two capacitors and four resistors as passive elements, which all are grounded. The circuit simultaneously provides the three basic filter functions, namely bandpass (BP), highpass (HP) and lowpass (LP) functions. The output signals

High temperatures and eminent thermal variations of processors create severe challenges in system reliability, and cooling costs. Therefore, power and thermal management have become prominent issues of portable computer systems. Dynamic threshold hopping and supply voltage scaling (DTSVS) is an effective low-power design technique for reducing dissipated power. The technique adjusts the body bias (VBB) or threshold voltage (Vth) and, correspondingly, the supply voltage (Vdd) adaptively in order to obtain a minimum power consumption and extend the ifetime on a revolutionary scale. In this study, the optimal simultaneous combination set of the threshold and supply voltage (Vth-Vdd) scaling is proposed to reduce power dissipation in the core of high-performance portable processors. Analysis and SPICE simulations are used to evaluate the presented theoretical basics and fundamentals. To ensu...
