This paper deals with the solution for a wideband low-pass filter that can be used for filtering the input currents of switching converters, which are distorted by the switching frequency of PWM. Initially, the filter was proposed for the special type of ... see more

Available photovoltaic (PV) systems show a prolonged transient response, when integrated into the power grid via active filters. On one hand, the conventional low-pass filter, employed within the integrated PV system, works with a large delay, particularl... see more

First-order all-pass filter circuits, both non-inverting and inverting, could be the focus of this article, which could include the design and implementation of first-order all-pass filter circuits. Using a standard integrated circuit (IC): AD830, as well... see more

Linear Delta Modulation (DM) is applicable to processing of signals in digital systems of telecommunication. One of most interesting kind of LDM is Adaptative DM (ADM). This Work presents method of using ADM for low-pass digital filtration.

Filters occupy important acts in several Radio Frequency microwave applications. Several applications such as wireless communications still challenge RF/microwave filters with strict requirements such as smaller size, higher performance, lighter weight, a... see more

This paper presents a novel microstrip lowpass filter. The proposed filter consists of two high impedance cells, which are integrated by a stub loaded transmission line. A rectangular stub is utilized to reduce the overall circuit size so that it has a co... see more

The paper presents an implementation of ultra low voltage second generation current conveyor (ULV-CCII). The methodology adopted for the design is the use of level shifting stage to lower the effective threshold voltage of the PMOS differential pair trans... see more

In this study, the proposed bandpass filter (BPF) connects an interdigital and a spiral capacitor in series between the two symmetrical halves of a circular intertwined spiral inductor. For the mass production of devices and to achieve a higher accuracy a... see more

Voltage and current harmonics produced by nonlinear loads which reduce electrical power quality and energy saving lamp is one of example of it. This research was done by performing studies in harmonic voltage and harmonic current from four different brand... see more
