Özet

In this study, a fractional capacitor order of alpha-based new fractional multivibrator topology is proposed. The new proposed circuit consists of a multioutput current follower transconductance amplifier (MO-CFTA) and a grounded fractional capacitor. The proposed topology offers electronically and independently control of output waveform amplitude, trigger levels, and oscillation period via relevant bias currents. The proposed circuit provides higher oscillation frequency in comparison with normal multivibrator. The proposed circuit is simulated via SPICE and 0.18 mu m TSMC technology parameters. Furthermore, the introduced concepts are also verified experimentally.
