Received Jan 2, 2017 Revised Mar 2, 2017 Accepted Mar 16, 2017 This paper relates the new topology and simulations of a fully differential CMOS active filter for mm wave band applications. The advantages of the differential topology over the single ended one are discussed and the quality factor is tuned to insure application requirements, including narrow bandwidth and high selectivity due to a...

An active filter with a 50 Ω buffer suitable as an anti-alias filter to drive a highly linear ADC is implemented in 0.13 μm SiGe BiCMOS. This 6th-order Chebyshev filter has a 3 dB cutoff frequency of 28.3 MHz and achieves 36.5 dBm OIP3. Nonlinear digital equalization further improves OIP3 to 43.6 dBm. Measurements show 92 dB of rejection at the stopband and a gain of 49 dB. The measured in-band...

The principle of recursive filters is well known in digital filtering. This paper deals with active recursive filters. A new design approach is presented. It will be shown that how active elements can be used in the design of amplification elements and large microwave time delay. The analytical and computer-simulated results will be presented for an active bandpass filter in the C-band. Key-Wor...

The paper presents application of a direct current control (DCC) method in a three-phase parallel active power filter. The shunt active power filter is employed to compensate the fundamental reactive power and harmonic distortion of non-linear loads. Due to its inverter-like topology with known parameters in the filter branch, the predictive DCC method was implemented to reduce the filter commu...

The main objective of this work is to propose a mathematical model for the differential sticking coefficient of clayey drilling fluids with a lubricant as an additive and evaluate the influence of differential pressure and lubricant content on filter cake thickness and permeability. Tests were carried out on fluids composed of water and 4.86% of active bentonite clay prepared in Hamilton Beach ...

The OTA is an amplifier whose differential input voltage produces an output current. Thus, it is a voltage controlled current source. Operational transconductance amplifier is one of the most significant building-blocks in integrated continuous-time filters. We show that the operational transconductance amplifier (OTA), as the active element in basic building blocks. In this paper Low pass filt...

This paper describes the development of a low cost shunt active power filter with digital control, which allows dynamic power factor correction and both harmonics and zero-sequence current compensation. The active filter controller is based on the instantaneous power theory (p-q theory) and was implemented using a standard 16 bits microcontroller. The p-q theory is introduced followed by the pr...

The fast growth of wireless applications in recent years has driven intense efforts to design highly integrated, high-performance, low-cost RFICs. Both low-IF [33]-[37] and double-quadrature [38]-[40] architectures have been adopted as promising receiver topologies to realize these design goals because they combine the advantages of heterodyne and direct-conversion architectures. In the low-IF ...
