ABSTRACT:
A pipeline ADC (Analog to Digital Converter) unit is provided that has a first and a second multi-stage portion. The first multi-stage portion has a first plurality of converter stages for converting a first analog signal to a first digital signal having a first digital resolution. The second portion has a second plurality of converter stages to convert a second analog signal to a second digital signal having a second digital resolution. The second plurality includes the first plurality. The pipeline ADC unit selectively uses either the first plurality of stages alone, or the second plurality. The pipeline ADC unit may be used in a WLAN (Wireless Local Area Network) communication device.
