Abstract :
A description is presented of the design of a versatile analog building block, termed an operational floating conveyor (OFC). The OFC has similar transmission properties to a current-feedback op amp, but with a differential current output which allows accurate output current sampling. This feature increases device versatility and enables accurate closed loop current amplifier topologies to be realized, including an accurate closed loop current conveyor. As a further development, the technique of active compensation is applied to the OFC to achieve very high performance current amplifier topologies
