Multifunctional current-mode filter with dual-parameter control of the pole frequency

New Multifunctional Frequency Filter Working in Current-mode

Increasing demands on circuits with low supply voltage and low power consumption lead to the realization of analogue circuits working in the current-mode. In this paper a new topology is presented of multifunctional frequency filter SIMO (Single Input Multiple Output) working the in currentmode. The proposed circuit is realized using four second-generation current conveyors and six passive elem...

Constant Frequency Hysteresis Current Control of Shunt Active Filter

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Nonlinear Sliding Mode Control Design for Shunt Active Power Filter with the Minimization of Load Current

This paper proposes a new method of sliding mode base controller for shunt active power filter to compensate the harmonic currents of a load. In this controller there isn't any need to PI DC voltage controller to regulate the DC capacitor voltage of shunt active power filter. In this method, first the reference currents of shunt active power filter that should be tracked to reduce or eliminate ...

Highly Selective Suspended Stripline Dual- Mode Filter

Miniature bandpass filter constructions based on a novel dual-mode suspended stripline resonator are proposed. Because of a special structure of the resonator, the frequencies of two first oscillation modes may be brought closer together. That allows realizing narrowband filters with the wide upper stopband. The filters have low insertion loss in the passband at small dimensions. Several transm...
