Highly digitized RF Receiver for Software Defined Radio
RF bandpass Sigma-Delta modulators have been suggested as potential candidates for RF ADCs dedicated to highly digitized receivers. Nevertheless, the measured Dynamic Range (DR) of state-of-the-art RF bandpass Sigma-Delta ADCs is not sufficient to satisfy the requirements of wireless communication standards.
In this work we propose a complete SDR receiver based on an RF bandpass Sigma-Delta ADC with an increased DR capable of satisfying several wireless communication standards.
The main contribution of this work can be summarized in the following: - A highly linear LNA with 20dB variable gain - Efficient Implementation of Poly-Phase decomposition decimation filters - A low-power Digital RF mixer for up and down-conversion - Design and implementation of the 1st complete SDR receiver based on an RF Sigma-Delta ADC. The receiver is suitable for 3 different communication standards (Zigbee, Bluetooth and WiFi) operating at 2.4GHz ISM-band.
