摘要

In this short paper, a recently proposed Active RC biquad using a single OTA and it’s modification to realize cascadability is studied using an opamp in place of OTA and resulting opamp-based filter is compared with the well-known Multiple-feedback Active RC filter using opamp regarding the capacitor spread, pole-frequency and pole-Q deviations due to the variation in the passive component values, finite dc gain and finite Gain Bandwidth Product of the opamp.
