dc.description.abstractThis paper presents a new Elliptic ladder bandpass (BP) filter based on MO-OTA. This RLC ladder low-pass (LP) prototype and network transformation are used to create the band-pass signal flow graph (SFG). From SFG, the integrators and differentiator are required to realize the BP Elliptic filter with low-complexity configuration. The integrator and differentiator circuits can generally be obtained based on OTA-C technique. Lossy and lossless integrators and differentiators based on MO-OTA(s) are straight-forward applied to SFG for achieving the designed filter. Based on this technique, the circuit is obviously apparent that the final circuit has low-complexity and low-component count compared with the conventional technique. This proposed BP Elliptic filter contains only 10 bipolar MO-OTAs and 8 grounded capacitors. The frequency responses can be tuned between 2kHz and 100kHz through the bias currents of OTA. The simulation results are carried out by PSpice and agreed well with theory anticipation.
