This paper presents a single-inductor dual-output (SIDO) boost DC-DC converter with an adaptive freewheel switching technique. Due to the adoption of freewheel switching duration averaging, the optimal freewheel durations in each phase of the SIDO converter are acquired within one switching cycle. The optimal freewheel switching duration improves the efficiency of the SIDO converter, especially during...
This paper presents an embedded power management module with adaptive on-chip power processing schemes, tailored for next-generation power-aware VLSI systems. The module comprises a single-inductor multiple-output (SIMO) power converter and a software-defined, digital controller. By using a digital control, the entire converter can be integrated with microprocessor units (MPUs). This enables a hardware-software...
A delay-locked loop (DLL) regulated single-inductor multiple-output (SIMO) power converter is presented. It takes advantage of the fast phase locking property of a DLL to identify the SIMO converter's regulation errors between the output voltages and their corresponding references. In response to these errors, an adaptive peak current modulation technique is proposed to adjust the instantaneous duty...
