Abstract

PURPOSE:To select an extremely small base resistance to improve S/N at the area and the time having no unnecessary disturbance signal and to select freely the base resistance to attenuate the disturbance signal and to improve S/N at the area and the time having the unnecessary disturbance signal, by forming the input circuit of an amplifier circuit into plural circuits of different base resistance.
