High-performance Bluetooth transmitters using two-point delta-sigma modulation

An advanced hut efficient design technique has been developed for applying two-point delta-sigma modulation (TPDSM) to Bluetooth transmitters. Various design parameters. including phase noise, quantisation noise, phase-locked loop stable time and mismatch between two modulation points, can be overall taken into account to achieve the excellent performance. Experimental results have further verified the proposed design methodology.
