一种采用连续时间可重构Delta-Sigma调制器的高效率低开关噪声Buck变换器

This paper presents a delta-sigma modulation control scheme for buck converters that features a reconfigurable loop filter with a scalable sampling frequency for effective switching noise reduction and high conversion efficiency. Depending on the load current, the proposed controller changes the sampling frequency along with the delta-sigma modulator (DSM) structure to transform between third- and...
