PURPOSE: To make production simple and easy by changing the order of sequences of rescaling operations and rectification operations. CONSTITUTION: This device consists of amplifiers 12, 14, 16, 18, and 20 which generate amplified versions of an input voltage of an input terminal 10, rectifiers 22, 24, 26, 28, and 30 which rectify the amplified versions to output rectified versions of an output voltage, voltage-current converters 32, 34, 36, and 40 which rescale and convert the rectified versions to the output voltage, and means 42, 44, 46, 48, and 50 which sum up currents to generate a totalized current in an output terminal 60. Sub-circuits which generate various versions of the input voltage are constituted in the same manner as stages which rectify various versions, and a conventional resistance ladder circuit is avoided. Consequently, each sequence has a module structure which can be easily extended by addition of a module provided with an amplifier, a rectifier, and a rescaling and conversion unit. |
