摘要:
The functionality of a variable gain controlled amplifier and a tree mixer are combined to provide a variable gain controlled mixer. In constructing the combination, both the current-to-voltage conversion output stage of the mixer, and the voltage-to-current conversion input stage of the variable gain amplifier are removed. Both the variable gain stage and the mixing stage are connected in parallel to modify the input current. Other configurations are provided, including a single balanced mixer, and a folded mixer.
