Abstract

PURPOSE:To enable the adjustment of voltage at the crossing point, by completely making agreement the crossing point of the current switch consisting of differential amplifier of a pair of transistors with the threshold level. CONSTITUTION:The current switch 40 has the differential amplifying circuit 51 consisting of a pair of transistors 41, 42 and the differential amplifying circuit 52 of a pair of transistors 43, 44, and the base of the transistors 42, 43 is set to a given level with the level setter 45 commonly, and the time difference of the crossing point converted with the output OUT and OUT' to the input IN and IN', i.e., the shift amount Y is set. When the input starts the change and the input IN' intersects the level Y at time t3, the output OUT' only is selected, and the input IN intersects the level Y at time t4, the output OUT is selected and after that, the both are crossed at the crossing point X. The shift up or down the crossing point X is made by changing the level of the level setter 45.
