Abstract
In this communication, an improved multifunction network configuration realizable with only two Current Feedback Operational Amplifiers (CFOAs) has been introduced which can realise (i) a universal filter (ii) two different grounded capacitor single resistance controlled oscillators (GC-SRCOs) and (iii) two positive and two negative synthetic grounded inductors, by altering certain network connections with a variety of useful characteristics and features, as compared to a similar circuit presented earlier. The workability of the various modes of operation of the proposed circuit configuration has been verified through SPICE simulations as well as hardware implementations based on commercial-off-the-shelf (COTS) AD844-type CFOAs.
期刊介绍:
AEÜ is an international scientific journal which publishes both original works and invited tutorials. The journal''s scope covers all aspects of theory and design of circuits, systems and devices for electronics, signal processing, and communication, including:
signal and system theory, digital signal processing
network theory and circuit design
information theory, communication theory and techniques, modulation, source and channel coding
switching theory and techniques, communication protocols
optical communications
microwave theory and techniques, radar, sonar
antennas, wave propagation
AEÜ publishes full papers and letters with very short turn around time but a high standard review process. Review cycles are typically finished within twelve weeks by application of modern electronic communication facilities.
