Abstract
Mobile terminal design is made simpler by providing an attenuation circuit having a selectable amount of attenuation within an integrated circuit. In one embodiment, a plurality of input pins are provided so as to connect to different points of the attenuation circuit. By selecting a particular input pin, a given amount of attenuation is available between the chosen input pin and the output pin. In a second embodiment, resistors within the attenuation circuit are selectively grounded to vary the amount of attenuation between the input pin and the output pin.
