Abstract
A gain circuit includes an analog section with variable gain and a digital section with variable gain. The gain steps for the digital section have a higher resolution than the gain steps for the analog section. In some implementations, gain steps can be achieved much finer than 0.1 db or less without sensitivity to device tolerances.
