Abstract
with their corresponding gate drivers and level shifters onto a single die using 180 nm BCD technology. On the other hand, all passive components, including the PR, flying capacitors, and bootstrap capacitors, are implemented off-chip. Additionally, due to the complexity of the control timing, off-chip digital control is utilized. A. Floating Gate Driving Strategy In this design, all of the power switches in the DSPPR are implemented by on-chip nMOS transistors, as shown in Fig. 4. Since multipl
