Abstract
PURPOSE:To obtain a voltage division circuit which extracts the voltage fractionated accurately by means of a comparatively small number of the resistance element featuring the accurate value plus the resistance circuit network to which the connection alteration can be given from the outside. CONSTITUTION:For serial resistance circuit group SRR for voltage division, resistance circuit networks RR-A and RR-B with the resistance value switched by the contact plus voltages VP and VQ are connected across the circuit group, and then divided voltages Vm-Vn are delivered through the resistance connection point. A number of switches SW-A1...plus SW-B1... within networks RR-A and RR-B operate complementarily and in a pair respectively, and then the control is given so that the sum of the resistance value networks RR-A and RR-B possess may always be constant. Voltages Vm-Vn are shifted by the optional fixed amount by varying the resistance values of RR-A and RR-B under the conditions stated above. As a result, an extremely large number of accurate potential levels can be obtained only by the siwtch operation.
