Abstract :
A microtransformer that is monolithically integrated with rectifier diodes is developed as the first step toward developing a monolithic microswitching converter that can be integrated with semiconductor devices and magnetic components. This microtransformer consists of planar coils and CoZrRe amorphous magnetic layers on Si substrate. Two Schottky barrier diodes are formed on the Si substrate and directly connected to a secondary coil. It is confirmed that this new microtransformer chip successfully performs both conversion and rectifying functions
