OTA-C TRANSIMPEDANCE BIQUADS DERIVED FROM PASSIVE FILTERS

Dattaguru V. Kamath


This paper presents the new OTA-C transimpedance second-order continuous-time filters based on passive circuits using component substitution method. The resistor and inductor in these biquads are realized using OTA-C counterparts. The proposed biquads are attractive due to their advantageous features like ease of design, good sensitivity and orthogonal tunability of pole-Q. The biquads have been simulated using practical OTAs as well as their behavioral macro-model and the results are given to verify the theoretical analysis.
