  • Process independent voltage controlled logarithmic attenuator having a low distortion and method therefor
    Patent number: 7453307
    Abstract: A process independent voltage controlled logarithmic attenuator has an attenuator control stage block having a first input coupled to a controlled input and a second input coupled to an offset generator. An attenuator transistor is coupled to the attenuator controlled stage block. An output of the attenuator controlled stage block is both slope and maximum voltage definable for a process independent design.
