“…In many analog signal processing applications, an active mixed-mode universal biquadratic filter (MUBF) with input voltages and/or currents, and output voltages and/or currents, is necessarily required. Over the last decade, numerous universal biquad filter realizations in mixed-mode operations based on different active components have already been developed in [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ].…”

This article presents the circuit designs for a mixed-mode universal biquadratic filter and a dual-mode quadrature oscillator, both of which use a single voltage differencing gain amplifier (VDGA), one resistor, and two capacitors. The proposed circuit has the following performance characteristics: (i) simultaneous implementation of standard biquadratic filter functions with three inputs and two outputs in all four possible modes, namely, voltage-mode (VM), current-mode (CM), trans-admittance-mode (TAM), and trans-impedance-mode (TIM); (ii) electronic adjustment of the natural angular frequency and independently single-resistance controllable high-quality factor; (iii) performing a dual-mode quadrature oscillator with simultaneous voltage and current output responses; (iv) orthogonal resistive and/or electronic control of the oscillation condition and frequency; (v) employing all grounded passive components in the quadrature oscillator function; and (vi) simpler topology due to the use of a single VDGA. VDGA non-idealities and parasitic elements are also investigated and analyzed in terms of their influence on circuit performance. To prove the study hypotheses, computer simulations with TSMC 0.18 μm CMOS technology and experimental confirmatory testing with off-the-shelf integrated circuits LM13600 have been performed.

Two New and Improved Electronically Adjustable Voltage-Mode Multifunction Biquadratic Filters With Independent Control of Band-Pass, High-Pass, and Low-Pass/Regular Notch Filter Gains

et al. 2023

View full text Add to dashboard Cite

In this study, two new and improved electronically adjustable voltage-mode (VM) biquadratic filters using three off-the-shelf LT1228 integrated circuits (ICs), two grounded capacitors (GCs), and six resistors are proposed for independent control of the band-pass (BP), high-pass (HP), and low-pass/regular notch (LPN/RN) filter gains. Each proposed electronically adjustable VM multifunction biquadratic filter has one input and six output voltages, enabling simultaneous realization of one low-pass (LP), two BP, two HP, and one LPN/RN filtering responses from the same configuration. Each filter parameter, namely the pole angular frequency (ω o ) and quality factor (Q), can be electronically controlled and orthogonally adjusted by the corresponding LT1228 bias current I B . In special cases, the parameters of ω o and Q can be electronically controlled and independently adjusted. Each electronically adjustable VM multifunction biquadratic filter has one high input impedance and three low output impedances for independent control of BP, HP, and LPN/RN filter gains. Due to its one high input impedance and three low output impedances, each proposed filter is suitable for cascaded VM circuits without external voltage buffers. Pspice simulations are used to verify the theoretical structure analysis of each proposed LT1228-based electronically adjustable VM multifunction biquadratic filter. Furthermore, experimental tests are performed using three off-theshelf LT1228 ICs, and several passive components to verify and evaluate the performance of each proposed LT1228-based biquadratic filter.INDEX TERMS LT1228, analog circuit design, integrated circuits, voltage-mode, filters.
