This paper presents a low-voltage nano-power multiple-input operational transconductance amplifier (MI-OTA) with high linearity performance and increased input voltage swing. The enhanced performances are achieved thanks to employing several techniques as the bulk-driven, source-degeneration, self-cascode negative conductance along concept of signal attenuation formed by MOS transistor. MI-OTA ...

In the last few years, several microwave filter design with band-pass response have been proposed for ultra-wideband (UWB) application. Among various microwave filter design, microstrip filter are mostly used by researcher due to their low profile, light weight, easy to fabricate and low cost. Conventional microstrip filter can be in any shape whether circular, rectangular or elliptical but som...

The design of an optimized near-perfect reconstruction (NPR) type trans-multiplexer has been proposed. Cosine modulation has been used to design the synthesis and analysis sections of the trans-multiplexer. The design of transmultiplexer was reduced to design of single low-pass prototype FIR filter which is designed using variable window function (Kaiser, Cosh and DolphChebyshev). An unconstrai...

The superconducting band-pass filter has small insertion loss and excellent out-of-band rejection properties. It has been put to practical use in a number of applications. However, in order to expand its range of application, a tuning technique that can restore the filter characteristics is needed. We propose an automatic tuning system using a trimming library and checked the feasibility of the...

The power calculation is an indispensable element in droop-controlled inverters because the bandwidth of measured has a direct impact on controller performance. This paper proposes fast and accurate algorithm based combined Second Order Generalized Integrator (SOGI) filters stationary coordinates for three-phase system, which takes into consideration use nonlinear loads. scheme formed by two-st...
