Abstract :
The definition, applications, and design of operational floating amplifiers (OFAs) are described. The OFA is similar in some respects to an operational transconductance amplifier (OTA) with a differential output. The OFA accurately equates two voltages connected to the terminals of the input port, like a standard operational amplifier, but, in addition, an OFA accurately equates two currents connected to the terminals of the output port. Specific applications are given, such as voltage-to-current converters, gyrators, and filters. The design of class-A and class-AB OFAs based on several topologies is addressed
