Some time back, Kircay reported an electronically-tunable current-mode square-root-domain first-order filter capable of realizing low-pass (LP), high-pass (HP) and all-pass (AP) filter functions. When simulated in SPICE, Kircay’s circuit has been found to exhibit DC offsets in case of LP and AP responses and incorrect transient response in case of HP response. In this paper, an improved circuit overcoming these difficulties/deficiencies has been suggested and its workability of the improved circuit as well as its capability in meeting the intended objectives has been demonstrated by SPICE simulation results.

The memristor has drawn the worldwide attention since it has been discovered at HP laboratory on 1 May 2008. Since then many researchers are taking efforts to find its applications in various areas. In this paper, we study the filter characteristics of first-order low pass and high pass filters employing memristor with a capacitor. The paper provides a comparative analysis between low pass and high pass filter circuits that utilizing ordinary resistor or memristor with a capacitor. The theoretical analyzes are verified with SPICE simulation results using a memristor SPICE model with nonlinear dopant drift and MATLAB environment. The effect of change of the input frequency and initial resistance value of memristor on the cut-off frequencies of the presented low pass and high pass filters are investigated. The memory effect of memristor is represented by simulation results.

The dependence of the dynamic range of the phase generated carrier (PGC) technique on low-pass filters passbands is investigated using a simulation model. A nonlinear character of this dependence, which could lead to dynamic range limitations or measurement uncertainty, is presented for the first time. A detailed theoretical analysis is provided to verify the simulation results and these results are consistent with performed calculations. The method for the calculation of low-pass filters passbands according to the required dynamic range upper limit is proposed.

In this paper, a new voltage-mode (VM) multifunctional filter comprising two second-generation current conveyors (CCIIs) is proposed. The proposed filter with one input and three outputs is also composed of three resistors and two grounded capacitors. The proposed filter has high input impedance; thus, it can be easily connected with other VM circuits. The proposed filter can simultaneously provide low-pass (LP), band-pass (BP) and high-pass (HP) responses. A number of time domain and frequency domain simulation results are included to confirm the claimed theory.

Abstract In this manuscript, two different topologies are presented for the realization of a conventional filter/inverse filter using the Four Terminal Floating Nullor Transconductance Amplifier (FTFNTA). The first topology can synthesize the inverse low-pass (ILP), inverse high-pass (IHP), and inverse band-pass (IBP) filter with applicable impedance choices. Subsequently, another topology that can synthesize conventional low-pass (LP), and band-pass (BP) active filter, as well as inverse high-pass (IHP), and inverse band-pass (IBP) filter from the same circuit topology with a viable solution of impedances as resistor/capacitor. To verify the workability of both topologies, SPICE simulation is performed using 180nm CMOS TSMC technology.

In this paper, eight new Frequency Dependent Negative Resistance (FDNR) circuits using two current conveyors or inverting current conveyors or a combination of the two types are introduced. The proposed circuits are canonic and they use two grounded capacitors and one floating resistor. The generation of grounded capacitor minimum passive component oscillators from the FDNR circuits is also considered. It is found that two of the recently reported attractive oscillators are among the family of the generated oscillator circuits. Additional six new oscillator circuits based on the FDNR circuits are introduced in this paper. Spice simulation results using technology: SCN 05 feature size 0.5 μm, MOSIS Vendor: AGILENT to demonstrate the practicality of the proposed oscillators are included.
