To improve the power delivery in System-on-Chips (SoCs), this paper proposes a single-input-multi-output (SIMO) hybrid converter to obtain fast response time, low cross-regulation, and 87% peak efficiency by using a multi-output hybrid power stage and dual-switching-frequency technique. The multiple-output hybrid power stage improves the conversion efficiency without sacrificing the output voltage range, and the dual-switching-frequency technique enhances the response time and cross-regulation performance. The proposed SIMO hybrid converter achieves 87.5% peak efficiency with an output voltage range from 0.4V to 1.6V for all outputs and a total maximum load current of 450mAAdditionally, it achieves less than 0.01mA/mV cross-regulation and less than 20mV overshoot at full-load step transient response.

null (Ed.)This paper presents an analytical model for calculating the output voltage and the power efficiency of multi-stage multi-output (MSMO) DC-DC converters (DDC) that use charge pump cells for boosting the voltage. Various cases such as multi-output current consumption and its effects on the output voltage and the power efficiency are studied. Based on the model, a tapered design approach is proposed that can bolster the power efficiency and lower the output voltage drop of MSMO DDCs. Moreover, a charge-pump-based DDC is introduced and designed to verify the proposed model. Simulation results using a standard high-voltage 180-nm CMOS technology affirms the accuracy of the presented model.more » « less

With the increasing complexity of highly integrated system on chips (SoCs), the power management system (PMS) is required to provide several power supplies efficiently for individual blocks. This paper presents a single-inductor multiple outputs (SIMO) an inductor-first hybrid converter that generates three outputs between 0.4V and 1.6V from a 1.8V input. The proposed multiple-output hybrid power stage can improve the conversion efficiency by reducing inductor current while extending the output voltage range compared with the existing hybrid topologies. In addition, the proposed converter employs an on-chip switched-capacitor power stage (SCPS) with a dual switching frequency technique, resulting in a fast response time, low cross-regulation, and reduced number of on-chip pads. Measurement results show that the converter achieves a peak efficiency of 87.5% with a maximum output current of 450mA. The converter is integrated with a fast voltage regulation loop with a 500MHz system clock to achieve less than 0.01mA/mV cross-regulation and a maximum 20mV overshoot at full-load transient response. The design is fabricated in the standard 180nm CMOS technologymore » « less

null (Ed.)A new high-voltage-gain non-isolated dc-dc topology for applications in renewable energies is proposed. A coupled inductor with three windings is used to increase the proposed topology voltage gain. In addition to increasing the voltage gain, the proposed topology also has other prominent features including continuous input current and zero dc magnetizing inductance current, which reduces the losses and size of coupled inductor core. Furthermore, the continuous input current guarantees a low-volume input filter, which is essential for renewable energy applications. The leakage inductor stored energy is recycled via the diode and capacitor and transferred to the converter output for increasing the efficiency and reducing voltage stresses on the converter components.more » « less
