Biquad Filter

A novel universal current-mode filter with three inputs and one high imedance output is presented. The proposed circuit uses four plus-type second-generation current-conveyors, grounded resistors and grounded capacitors. The proposed circuit enjoys low active and passive sensitivities and independent control of the parametersω0/Q0using grounded resistors.

A Current

This research article explores the possible applications of voltage differencing current conveyor (VDCC), as a current mode universal filter and a sinusoidal oscillator. Without the need for an additional active/passive element, a very simple hardware modification makes it a dual-mode quadrature oscillator from the filter configuration. Both the proposed circuit requires only two VDCC and all grounded passive elements, hence a preferable choice for integration. The filter has some desirable features such as availability of all five explicit outputs, independent tunability of filter parameters. Availability of explicit quadrature current outputs, independence in start and frequency of oscillations, makes it a better oscillator design. Apart from prevalent CMOS simulation results, VDCC is also realized and experimentally tested using the off-the-shelf integrated circuit. All the pen and paper analysis such as non-ideal, sensitivity and parasitic analysis supports the design.

This paper describes the conception of the current follower transconductance amplifier (CFTA) with electronically and linearly current tunable. The newly modified element is realized based on the use of transconductance cells (Gms) as core circuits. The advantage of this element is that the current transfer ratios (iz/ipandix/iz) can be tuned electronically and linearly by adjusting external DC bias currents. The circuit is designed and analyzed in 0.35 μm TSMC CMOS technology. Simulation results for the circuit with ±1.25 V supply voltages show that it consumes only 0.43 mw quiescent power with 70 MHz bandwidth. As an application example, a current-mode KHN biquad filter is designed and simulated.

This paper presents a versatile universal current-mode and transresistance-mode biquadratic filter using only two multiple outputs second-generation current conveyors (MOCCIIs), two grounded capacitors, and three grounded resistors. The proposed configuration can realize all five standard filtering functions from one current-output terminal and one voltage-output terminal, and also provide all these filtering functions from different current-output and voltage-output terminals without changing the filter topology. Moreover, the proposed biquad filter still achieves many advantages like the employment of all grounded passive components, and the minimum number of active component counts, in addition to having no need of inverting-type input signals or double-type input signals for the use of special input signals, high output impedance and low sensitivity performance. H-Spice simulation results confirm the theory.
