摘要：
The operational floating amplifier (OFA) is the most general 'nullor' implementation, which is a basic active two-port network element. The definition, applications, and design of OFAs are described. 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, e.g., current amplifiers, voltage-to-current converters, and gyrators. The design of class-A and class-AB OFAs based on several topologies is covered.
