- Use In-the-Loop Gain Control to Extend Dynamic Range.
  Modern communications systems are demanding more dynamic range than current analog-to-digital converters (ADCs) can support. One way to gain system dynamic range is to use a digitally-controlled variable gain amplifier (DVGA) with a high-speed, high-resolution ADC in a digitally-controlled AGC loop.
