Abstract

This paper presents new OTA-C transadmittance-mode/voltage-mode continuous-time biquads based on passive circuits using element substitution method. The grounded/ floating resistor and inductor in these biquads are realized using active OTA-C simulation. The current through these OTA-C simulated resistor and inductor elements is used to implement useful transadmittance-mode transfer unctions.The current through OTA simulated resistor/ inductor is made available using a dual output OTA (DO-OTA). 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 CMOS OTA circuit as well as their behavioral macro-model and the results are given to verify the theoretical analysis
