In recent times, dynamic supply voltage scaling (DVS) has been extensively employed to minimize the power and energy of VLSI systems. Also, sub-threshold circuits are becoming more popular. At the same time, the reliability of VLSI systems has become a major concern under Single Event Upsets (SEUs). SEUs are very problematic even for circuits operating at nominal voltages. With the increasing d...

Motivated by emerging battery operated applications that demand intensive computation in portable environments, techniques are investigated which reduce power consumption in CMOS digital circuits, by operating the devices at low currents and low voltages[1,2,3,4].It is known that MOS devices and circuits especially CMOS circuits consume relatively low power[5,6] . But there seems to be a need t...

Limited energy consumption in multimedia requires very low power circuits. In this paper we focused on leakage current minimization in single static random access memory (SRAM) cell in 90nm complementary metal oxide semiconductor (CMOS) technology. The leakage current mainly consists of sub threshold leakage current and gate leakage current in 90nm CMOS technology. So minimizing the sub thresho...

     Gamma-aminobutyric acid (GABA) is an important inhibitory transmitter in central nervous system and is involved in pathophysiology of epilepsy. Pentylenete-trazole (PTZ), a convulsant agent, partly acts via anion channel of GABAA receptor. Ivermectin, an antiparasitic agent and a GABAA agonist, has anticonvulsant effect in animal seizure models. Cholestasis increases ...

We assess both numerically and theoretically how external noise current affect the behavior of Leaky Integrate and Fire model. Integrate and fire model works better in asynchronous inputs environment in case of signal to noise ratio of efferent spike trains. External noise and sub threshold stimulus are subject to all the neurons. Response of the models is totally different to correlated inputs...

Noncentrosymmetric (NCS) tetrel pnictides have recently generated interest as nonlinear optical (NLO) materials due to their second harmonic generation (SHG) activity and large laser damage threshold (LDT). Herein nonmetal-rich silicon phosphides RuSi4P4 IrSi3P3 are synthesized characterized. Their crystal structures reinvestigated using single X-ray diffraction 29Si 31P magic angle spinning NM...
