Design of anti-jamming current-sensing circuit for current-mode buck regulator
电流模降压变换器抗干扰电流采样电路设计

A novel anti-jamming integrated CMOS current-sensing circuit for current-mode buck regulators is pre- sented. Based on the widely-used traditional current-sensing structure, anti-jamming performance is improved sig- nificantly by adding on-chip capacitors and one-shot circuit. Also the transient response is faster through the in- troduction of current offset. The circuit is concise, simple to implement and suits for SoC applications with single power supply.
