ABSTRACT:
Linear wide dynamic range variable gain amplifiers can be configured using a variable gain amplifier having an abbreviated gain control range in combination with a discrete attenuator controlled to select an attenuation from a predetermined set of attenuation values. The variable gain amplifier is configured to provide substantially linear gain control over the abbreviated gain control range, where the abbreviated gain control range is less than a total desired gain control range. The difference between adjacent attenuation values in the set of attenuation values is configured to be approximately less than or equal to the abbreviated gain control range.
