摘要： This squaring circuit has an input connected to the collector of a PNP transistor which has its emitter connected to the emitter of an NPN transistor. This NPN transistor has the collecotor maintained at a predetermined voltage and the base connected to the base of another NPN transistor. The latter NPN transistor has the collector connected to both a source of constant current and its base, and has the emitter maintained at a predetermined voltage and connected to the emitter of another PNP transistor which has its collector connected to an output of the circuit and its base connected to the base and the collector of the first mentioned PNP transistor which has its collector connected to the input. Both PNP transistors have approximately the same characteristics as both NPN transistors.
