A Low-EMI Buck Converter Suitable for Wireless Sensor Networks With Spur-Reduction Techniques

This paper presents a low electromagnetic interference buck converter for wireless sensor networks with the spur-reduction techniques. The proposed buck converter uses the third-order delta-sigma modulator (DSM) with its noise-shaping characteristic to achieve low output noise. The DSM is designed w...
