Item type:Publication, Active DURC notch filter(2014-01-01)This article present to voltage mode active notch filter using double capacitive layers uniformly distributed RC line (DURC) with the proposed active notch filter circuit configuration consists of one DURC, one resistance(R <inf>n</inf>). and a DC voltage gain amplifier. The parameters of the proposed circuit such as; α, β and K are adjustable the frequency responses with notch tunable frequency. The experimental and simulation results by MATLAB and PSPICE are showed god agreement with the theoretical. © 2014 IEEE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The voltage-mode TITO biquadratic filter based on CCDCVC and URC(2019-07-07)This paper presents the biquadratic filter with three input and two outputs (TITO) based on the current-controlled differential currentvoltage conveyor (CCDCVC) and uniformly distributed RC (URC) in the voltage-mode. The proposed circuit requires only two CCDCVC, one URC and one double capacitive layers uniformly distributed RC (DURC). This circuit has a functional filter to four types at first output and three type filters at the second output, and the characteristic insensitivities have low. We using the PSPICE simulation program to confirm the theoretical in this work. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Active URC sinusoidal oscillator(2014-01-01); This article presents a voltage mode sinusoidal oscillator using uniformly distributed RC line (URC) and voltage gain amplifier as active elements. The outputs of sinusoidal waveform with 0° from the configuration. The oscillation condition and oscillation frequency (ω<inf>0</inf>) of the proposed oscillator circuit are tunable by the amplifier gain (K) and the resistance ratio (β). The simulation results by MATLAB and PSPICE are good agreement with the theoretical analysis and also show that very low harmonic distortion is obtained. The proposed circuit is suitable for fabricating in LSI technology. © 2014 IEEE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The voltage-mode with triple-input single-output universal biquad filter using DURCs and CCCIIs(2014-10-03); ; Chutchavong, VansiaThis article presents a new voltage-mode with triple-input single-output universal biquad filter using double capacitive layers uniformly distributed RC lines (DURCs) and a second-generation current-controlled current conveyors (CCCIIs). The proposed universal biquad filter has possesses three inputs and single output for generate four filter types as low-pass filter (LPF), high-pass filter (HPF), band-pass filter (BPF) and notch filter (NF) in voltage responses, employs the minimum active and passive components and also provides low active and passive sensitivities at frequency cutoff in all realize filter. The property of the proposed circuit is simulation using PSPICE to verify the theory. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, On the design of active crossover network using double capacitive uniformly distributed RC filter(2015-07-14); This article presents the design of an active crossover network using double capacitive uniformly distributed RC filter (DURC). The proposed circuit includes the active DURC-based low-pass filter circuit together with the active high-pass filter circuit. The advantage property of this crossover network has flat magnitude response of crossover network signal and small phase difference. The proposed network also has low active and passive sensitivities. The simulation results by MATLAB and PSPICE in terms of the magnitude response, phase response, sensitivity and stability are approved the theoretical predictions.
