A square extraction circuit and electrical equipment

Abstract

The invention discloses a squaring operation circuit. The squaring operation circuit comprises an input matching circuit module, an inflection point adjusting circuit module, a Line segment generationcircuit module, a blocking circuit module and an output addition circuit module; the line segment generation circuit module is used for respectively adding the plurality of inflection point voltage signals output by the inflection point regulation circuit module and bias voltage signals regulated and output by the input matching circuit module according to the input voltage signals; the output summing circuit module outputs a plurality of different voltage signals to the output summing circuit module; the output summing circuit module is used for summing the plurality of different voltage signals so as to output square root signals proportional to the input voltage signals; The circuit is high in free combination degree; Unlimited accumulation can be achieved through different combinationmodes, output of a plurality of line segments is achieved, the blocking circuit module can cut off a bias voltage signal and output the bias voltage signal to the output addition circuit module whenan input voltage signal is lower than a blocking voltage, and in addition, the squaring operation circuit has the advantages of being simple in circuit structure, high in operation precision and low in cost.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a square extraction operation circuit and electrical equipment. Background technique [0002] At present, square extractors are mainly digital calculation square extractors. However, digital calculation square extractors can only calculate according to the rules that have been set in the digital calculation square extractors, and cannot achieve superposition through different combinations, making its peripheral The limitation of the circuit is large, which leads to the single function that the square extractor can complete, and it is not flexible to use. It can only complete the two-quadrant output, but cannot realize the four-quadrant output or although it can realize the four-quadrant output, its accuracy is very low. [0003] Therefore, the digital calculation square rooter in the traditional technical solution has the problem of being unable to realize t...
