| contents | This paper describes a SIMO DC-DC converter capable of generating all the required voltages (buck and boost) utilizing n-type transistors for the output switches. The design incorporates only one shared bootstrap capacitor and a single pad to connect the top plate of the off-chip bootstrap capacitor to the on-chip drivers. By utilizing one off-chip bootstrap capacitor and sharing it between the multiple outputs, this work presents a low cost and low area solution for implementing a SIMO DC-DC converter using n-type transistor switches. A prototype of the proposed SIMO DC-DC converter is fabricated in 180nm SILTERRA BCD Technology. |
