Item type:Publication, Two-Quadrant Current-Mode Logarithmic and Anti-logarithmic Amplifiers with Temperature CompensationThis paper proposes circuit topologies for realizing two-quadrant current-mode logarithmic and anti logarithmic amplifier configurations with temperature compensation. The design approach employs the translinear approach to generate the output currents that directly correspond to the absolute values of the logarithmic and anti logarithmic functions. The proposed circuits can operate at a low-level supply voltage of 2V with both input and output current signals. A detailed examination of the non-ideal circuit performance has also been considered. To validate their functionality and illustrate their superior thermal stability, the developed circuits have been simulated. All simulations were conducted via PSPICE for a real bipolar transistor model of the HFA3096 technology. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Voltage-mode universal filter with one input and five outputs using DDCCTAs and all-grounded passive components(2012-08-01); This paper presents a versatile voltage-mode universal active filter with one input and five output terminals. The proposed circuit is based on using the recently reported active building block, namely differential difference current conveyor transconductance amplifier (DDCCTA). It employs two DDCCTAs as active elements together with two resistors and two capacitors as passive elements, which are all grounded. The circuit simultaneously realizes all the five standard biquadratic filter functions; i.e.; lowpass (LP), bandpass (BP), highpass (HP), bandstop (BS) and allpass (AP), without changing circuit topology. The proposed circuit also has the advantage of high-input impedance terminal, and exhibits electronic tunability of its important parameters through the bias current of the DDCCTA as well as low sensitivity performance. PSPICE simulations using 0.5 μm MIETEC CMOS process are used to validate the theoretical predictions. © 2011 Elsevier Ltd.

Item type:Publication, Dual-mode multifunction filter realized with a single voltage differencing gain amplifier (vdga)(2021-01-01); ; Channumsin, OrapinThis article presents the dual-mode multifunction biquad filter realized employing only a single voltage differencing gain amplifier (VDGA), one resistor and three capacitors. The proposed filterwith one input and three outputs can configure as voltage-mode or current-mode filter circuit with the appropriate input injection choice. It can also synthesis the three standard filter functions, which are highpass, bandpass, and lowpass responses without modifying the circuit configuration. Orthogonal adjustment between the natural angular frequency (ωo) and the quality factor (Q) of the filter is achieved. Detail analysis of non-ideal VDGA effects and circuit component sensitivity are included. The circuit principle is verified by means of simulation results with TSMC 0.35-μm CMOS process parameters. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Structural generation of two integrator loop filters using CDTAs and grounded capacitors(2011-01-01); A versatile family of two integrator loop filter structures using current differencing transconductance amplifiers (CDTAs) and grounded capacitors is generated. The basic filter building blocks consist of current proportional blocks, current lossless integrators and a current lossy integrator based on the use of CDTAs as the major active components. It is demonstrated that the derived filter structures can realize a general class of second-order current transfer functions. Since the resulting structures contain only CDTAs and grounded capacitors, they are general and very appropriate for integration, cascading and electronic tuning. The influences of the CDTA non-idealities are also discussed. The functionality of the resulting filters has been verified by simulation results. © 2009 John Wiley & Sons, Ltd. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, High-Input-Impedance Four-Input Single-Output Voltage-Mode Biquadratic Filter with Only VDTAs and Grounded Capacitors(2022-01-01); This paper presents a voltage-mode universal biquadratic filter with voltage differencing transconductance amplifiers (VDTAs) as active components. The proposed filter comprises four inputs and a single output and can perform all five general biquadratic filter functions, namely lowpass, bandpass, highpass, bandstop, and allpass responses, without modifying the circuit architecture. It also offers the advantages of resistorless implementation with only two grounded capacitors, orthogonal adjustment of the natural angular frequency and the quality factor, as well as the absence of any constraint related to the values of input signals. Moreover, because the circuit contains all of the high input impedance levels, it may be cascaded without the requirement of additional buffers. The suggested filter's functioning has been validated by simulations using the PSPICE application. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Resistorless voltage-mode first-order allpass section using single current-controlled conveyor transconductance amplifier(2015-05-01); This paper presents an alternative configuration for realizing a canonical voltage-mode first-order allpass (AP) section with electronic tuning. The proposed circuit is composed of only one CCCTA and one floating capacitor, which results in a simple and resistorless structure. Its phase response can be adjusted electronically through the external dc bias currents of the CCCTA. Simulation results based on 0.35 μm BiCMOS process parameters with ± 0.75 V supply voltages are provided to demonstrate the performance of the proposed AP section. - Some of the metrics are blocked by yourconsent settings
