Abstract

PURPOSE:To output a signal current with small spike independently of the amplitude of an inputted switching signal by comparing the inputted switching signal with a reference voltage to generate the switching signal of opposite polarity subject to amplitude limit and using the switching signal so as to switch the path of the signal current. CONSTITUTION:A switching signal inputted from a switching signal input terminal 1 is given to a comparator 3. It is compared with the reference voltage V2 to switch the path giving a bias current from a bias current source 2. The bias current is converted into a voltage by a load Z1 or Z2 and outputted to a signal current switching circuit 4-a, from which the signal current from the current source 5 is given to an output terminal 6 or 7 switchingly. Since the said switching signal is subjected to amplitude limit by the loads Z1, Z2, the spike caused in the output signal is small.
