1. An attenuator component comprising:
a plurality of attenuator units each having an attenuation value that define a range of attenuation values, wherein some of the attenuation values comprise higher attenuation values and some of the attenuation values comprise lower attenuation values, wherein the plurality of attenuator units are coupled together so as to receive an input and an output signal that has a final attenuation value, and wherein each of the plurality of attenuator units has a first state where a first attenuation value is applied to an input signal to produce a first output, and a second state where a second attenuation value is applied to an input signal to produce a second output, wherein the first attenuation value is greater than the second attenuation value; and a control unit that in response to a logic signal selecting a final attenuation value, provides control signals to the plurality of attenuation units so that the plurality of attenuation units are placed into either the first state or the second state, wherein the control unit induces selected ones of the plurality of attenuation units having higher attenuation values to enter the second state after selected ones of the plurality of attenuation units having lower attenuation values enter the first state so as to reduce transient overshoot provided at the output during transition of the attenuator component from one attenuation level to another. |
