We show all-optical switching of an input infrared laser beam at 1310 nm by controlling the photoinduced retinal isomerization to tune the resonances in a silica microsphere coated with three bacteriorhodopsin BR protein monolayers. The all-optical tunable resonant coupler re-routes the infrared beam between two tapered fibers in 50 s using a low power 200 W green 532 nm and blue 405 nm pump be...

In this paper, we propose a leakage reduction technique. Because high leakage currents in deep submicron regimes are becoming a major contributor to total power dissipation of CMOS circuits. Sub threshold leakage current plays a very important role in power dissipation. So to reduce the sub threshold leakage current we proposed an adaptive voltage level (AVL) technique. Which optimize the overa...

Carbon Nanotube filed-effect transistor (CNFET) is one of the promising alternatives to the MOS transistors. The geometrydependent threshold voltage is one of the CNFET characteristics, which is used in the proposed design. In this paper, we present a novel high speed Adder-subtractor cell using CNFETs based on XOR gates and multiplexer. Presented design uses fourteen transistors, ten for full ...

In this manuscript, an unusual adaptive FIR filter using distributed arithmetic (DA) for area efficient design is implemented. DA is bit-serial computational action and uses parallel look-up table (LUTs) apprise and equivalent implementation of filtering and weight-update operations to appliance high throughput filter rates irrespective of the filter length. The full adder based conditional sig...

The paper presents current adder and subtractor circuits based on cascode current mirror with improved linearity and wide linear range. The proposed circuits can be used for analog signal processing applications such as amplifiers, operational transconductance amplifiers (OTA), Gm-C filters, etc. In the proposed circuits, cascode current mirror topology is employed to improve current mirroring ...
