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, 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.
