Abstract :
A transconductance amplifier has been designed and fabricated in monolithic form for use in implementing high-frequency active filters. The transconductance amplifier, known as a monolithic nullor, is a 3-terminal gain block that may be used to make very high-quality generalised immittance convertors. Simulated-inductance and FDNR active ladder filters have been implemented with this amplifier and are superior to the equivalent operational-amplifier derived active filters.
