Abstract
PURPOSE:To prevent noise due to alpha rays by adding a circuit comprising a transistor(TR) and a diode or the like to an emitter follower circuit so as to allow the noise due to the alpha rays to hardly pass through the emitter follower circuit. CONSTITUTION:Supposing that VIN, VOUT are at a low level at first. When the VIN transits to a high level, the substantial propagation path of the signal is sent to a circuit 16 and a TR 15, but since the VIN is inputted also to a TR 11, the potential of the emitter of the TR 11 rises quickly more than the voltage VOUT. As a result, the current flowing to the diode 12 and the resistor 13 is less than at a standstill state. This makes the rising of the emitter potential of the TR 15, that is, the VOUT faster, because much current in the TR 15 is used due to the charging of the load capacitance connected to the emitter.
