Compact size wearable devices require multiple supplies with relative large loading difference, which causes serious cross regulation, large ripple, and oscillation in single-inductor multiple-output (SIMO) DC–DC converter. Thus, a continuous conduction mode/green mode (CCM/GM) relative skip energy control (RSEC) in SIMO is proposed for wearable device power solution. Different from the conventional...
The proposed single-inductor dual-output (SIDO) converter can provide wide range in duty ratio control to convert input voltage 5–20V to dual output voltages 3.3V and 1.2V when its switching frequency is raised to 10MHz for compact size solution. The proposed synthesized waveform control (SWC) technique can emulate the inductor current without being affected by switching noise. Thus, the minimum allowable...
The proposed deep-standby mode (DSM) is used in 28nm power management unit (PMU) for long-term usage in active implantable medical devices (AIMD). The PMU can upgrade its normal mode with the proposed embedded auto-cancellation (EAC) technique in order to have high accuracy even if the battery is aging and the PVT variations occur. The test chip fabricated in 28nm CMOS process features low quiescent...
Single-inductor multiple-output (SIMO) DC-DC buck converters, which possess the advantage of compact size, are commonly implemented in portable electronics like mobile phones and tablets. However, their power efficiency is degraded considerably, as illustrated in Fig. 12.6.1, when multiple outputs are requested in a wide range, such as 1.2 to 3.3V for tablets. The use of P-MOSFET [1][2] and N-MOSFET...
