ABSTRACT:
An attenuator with a simple circuit configuration is and accurate attenuation includes four transistors connected in parallel between a connecting point on a main line and a ground. Since the transistors are individually brought into an “ON” state and an “OFF” state to function as “resistors” or “capacitors”, a desired attenuation be obtained by combinations of the ON and OFF states of the respective transistors.
