Abstract
A system () and method () are presented for calibrating an analog signal path () associated with an Ultra Wideband (UWB) receiver (). The analog signal path includes a plurality of analog gain stages (-), a local oscillator mixer stage (), a compensation stage (), and a converter stage (). An information signal includes whitened symbols (). When a predetermined number of whitened symbols are accumulated for one of a plurality of gain configurations, an arithmetic mean is calculated and used an offset value. The offset value is retrieved whenever the gain configuration is activated and applied at the compensation stage to reduce the offset.
