A new voltage-mode biquad with four inputs and four outputs using only two differential difference current conveyors (DDCCs), two grounded capacitors, and two resistors is proposed. The proposed circuit can act as a multifunction voltage-mode filter with one or three inputs and four outputs and can perform simultaneous realization of voltage-mode notch, highpass, bandpass, and lowpass filter signals from the four output terminals, respectively, without any component choice conditions. On the other hand, it also can act as a universal voltage-mode filter with four inputs and a single output and can realize five generic voltage-mode filter signals from the same configuration without any component-matching conditions. Finally, to verify our architecture, we have designed this analog filter chip with TSMC 0.35 μm 2P4M CMOS technology. This chip operates to 1.125 MHz and consumes 30.95 mW. The chip area of the analog filter is about 0.822 mm2.

This paper presents a second-order voltage-mode filter with three inputs and single-output voltage using single commercially available IC, one resistor, and two capacitors. The used commercially available IC, called LT1228, is manufactured by Linear Technology Corporation. The proposed filter is based on parallel RLC circuit. The filter provides five output filter responses, namely, band-pass (BP), band-reject (BR), low-pass (LP), high-pass (HP), and all-pass (AP) functions. The selection of each filter response can be done without the requirement of active and passive component matching condition. Furthermore, the natural frequency and quality factor are electronically controlled. Besides, the nonideal case is also investigated. The output voltage node exhibits low impedance. The experimental results can validate the theoretical analyses.

This paper introduces a novel voltage-mode multifunction biquadratic filter with single input and four outputs using two plus-type differential difference current conveyors (DDCCs) and four grounded passive components. The filter can realize inverting highpass, inverting bandpass, noninverting lowpass, and noninverting bandpass filter responses, simultaneously. It still maintains the following advantages: (i) using grounded capacitors attractive for integration and absorbing shunt parasitic capacitance, (ii) using grounded resistors at allXterminals of DDCCs suitable for the variations of filter parameters and absorbing series parasitic resistances at allXterminals of DDCCs, (iii) high-input impedance good for cascadability, (iv) no need to change the filter topology, (v) no need to component-matching conditions, (vi) low active and passive sensitivity performances, and (vii) simpler configuration due to the use of plus-type DDCCs only. HSPICE and MATLAB simulations results are provided to demonstrate the theoretical analysis.

This paper proposes a multi-input single-output (MISO) second-order active-C voltage mode (VM) universal filter using two second-generation current-controlled current conveyors (CCCIIs) and two equal-valued capacitors. The proposed circuit realizes low pass, band pass, high pass, all pass, and notch responses from the same topology. The filter uses-minimum number of passive components and no resistor which is suitable for IC Design. The filter enjoys low-sensitivity performance and exhibits electronic and orthogonal tunability of pole frequency () and quality factor () via bias current of CCCIIs. PSPICE simulation results confirm the theory.

A new voltage-mode (VM) biquad filter is presented, which employs four Current Conveyors (CC) along with five resistors and only two grounded capacitors, facilitates electronic control of filter parameters through grounded resistors (realizable by FETs/MOSFETs) and is suitable for IC implementation in bipolar or CMOS technology.

Matching Constraints

In this research three new grounded inductance simulators (GIS) are proposed. In addition, frequency dependent negative resistor (FDNR) and grounded capacitor (GC) simulators are also developed. The voltage differencing current conveyor (VDCC) is utilized in the design. All the developed simulator circuits need a single active block and only two grounded passive components. All the designed simulator circuits are perfectly tunable and did not suffer from passive component matching constraints. To demonstrate the performance of the inductor, FDNR and GC circuits they are employed in designing  current mode parallel RLC multifunction filter, low pass third order Butterworth filter and RLC resonance circuits. The VDCC is designed in 0.18μm CMOS technology parameters from TSMC and simulated in P-Spice software to prove the theoretical predictions.
