推出了一款全集成 0.18mum SiGe 同步降压 DC/DC 转换器，带有片上 LC 输出滤波器，支持最大输出电流 200mA，效率为 64%。该转换器采用 10μm 厚的电镀铜层来集成电感器和栅极电容器。 45MHz 的高开关频率、多相交错操作和快速迟滞控制将滤波电感器和电容器尺寸减小了两个数量级，从而实现了完全集成的转换器
A fully integrated 0.18mum SiGe synchronous buck DC/DC converter with an on-chip LC output filter supporting a maximum output current of 200mA and efficiency of 64% is presented. The converter utilizes a 10mum-thick electroplated copper layer for integrated inductors and gate capacitors. High switching frequency of 45MHz, multi-phase interleaved operation, and fast hysteretic control reduces the filter inductor and capacitor sizes by two orders of magnitude enabling a fully integrated converter
