Abstract

This paper presents the OTA-based current differencing buffered amplifier (CDBA), which has a simple configuration comprised four OTAs. The proposed circuit is ease of design and suitable for analog signal processing applications in both voltage and current modes. The first order allpass filters were implemented as the application examples in order to demonstrate the performances of the proposed CDBA. PSPICE analog simulation and the commercially available OTAs-based experimental results verifying the circuit performances are also included.
