In this paper, a new trans-admittance-mode biquad filter configuration based on two multi output voltage differencing transconductance amplifiers (MO-VDTAs) as newly active elements is proposed which also consists of two grounded MOS resistors and two capacitors with one of the capacitor is being permanently grounded. The proposed configuration is competent of realizing trans-admittance-mode lo...

Testing mixed-signal circuits is a difficult task due to defect modelling challenges, observability and controllability restrictions and ATE bandwidth limitations. In previous works, X-Y Zoning method has been proposed as a BIST technique for mixedsignal and analogue circuits. Some experiments showed its viability in detecting parametric deviations in analog cells. . In this paper the optimal X...

This article is an excellent introduction to analog filters. It covers the basic first and second order filter types as well as the advantages and disadvantages of passive and active filters. It derives and analyzes the basic biquad implementation using several op amp implementation examples. The world of filter design is often thought of as black magic because of the myriad of configurations, ...

This paper presents a switched-capacitor (SC) band-pass biquad using a simple quasi-unity gain amplifier. In sub-nanometer CMOS technologies the intrinsic gain of the transistors is low; this increases the difficulty of designing high gain amplifiers. The proposed SC filter is based on the Sallen-Key biquad and it requires only a simple low gain amplifier. A differential filter circuit, includi...

In this paper, a circuit employing current controlled current conveyor trans-conductance amplifiers (CCCCTAs) as active element is proposed which can function both as biquad filter and oscillator. It uses two CCCCTAs and two capacitors. As a biquad filter it can realizes all the standard filtering functions (low pass, band pass, high pass, band reject and all pass) in voltage-mode and provides ...

A new three-input and single-output current-mode biquad filter using one plus-type inverting second-generation current conveyors (ICCIIs), two grounded capacitors and two resistors is presented. This filter can simultaneously realize five generic low-pass, band-pass, high-pass, band-reject and all-pass filtering signals. H-Spice simulations with 0.35μm process are used to validate filter feasib...

In this paper, a new three input single output trans-admittance mode biquad universal filter is proposed, which employs only single active element, namely modified differential voltage current conveyor trans-conductance amplifier (MDVCCTA) and four passive elements in the form of two capacitors and two resistors. Two of the passive elements used in the proposed structure (one resistor and one c...
