The invention discloses a universal conversion circuit for converting grounding into floating ground. The universal conversion circuit comprises a differential amplification circuit, an in-phase proportional amplification circuit, an in-phase proportional voltage and current conversion circuit, a reverse proportional voltage and current conversion circuit and a circuit Z to be converted, and one end of the circuit Z to be converted is required to be grounded. The purpose is to solve the problem that an existing equivalent circuit needing one grounded end cannot achieve the floating function. According to the invention, electrical characteristics of ports a and b of the conversion circuit are equivalent to those of the to-be-converted circuit Z requiring one end to be grounded, and the ports a and b are not required to be grounded in use, so that the conversion circuit can be used as a floating equivalent circuit. An existing equivalent circuit with one end required to be grounded can be widely converted into a floating circuit, and high universality and practicability are achieved.
Description
technical field [0001] The patent of the invention relates to the field of equivalent circuit design, in particular to a general conversion circuit for converting a grounded equivalent circuit to a floating equivalent circuit. Background technique [0002] Currently, circuit design involves the use of circuit components without physical entities, such as negative resistance resistors, memristors, memcapacitors, and memristors. Usually, people use existing circuit components (resistors, capacitors, and inductors, etc.) and combine them with devices such as operational amplifiers to design equivalent circuits for negative resistance circuits, memristors, memcapacitors, and memristors. Sometimes, the designed equivalent circuit requires one end to be grounded, such as the equivalent circuit of negative resistance resistance, the equivalent circuit of quadratic nonlinear memristor, the equivalent circuit of cubic linear memristor, etc. [0003] The equivalent circuit that requi...
