Resource/performance optimization of hybrid inductive-capacitive converters

In the search for high power density, on-chip integrated converters, we consider new architectures based on Switched Capacitor Converters. These converters are suited for Power System on-Chip/in-Package (PSoC/PSiP) integration, enabling the use of lower voltage switches when compared to the converters based on inductors. The benefits of the SCC can be further exploited by taking advantage of their switching nature in combination with filtering inductors, forming a hybrid architecture as shown in Fig.1b. Indeed, the internal nodes of these converters provide many useful outputs with floating Pulsed-Width-Modulated voltages. This hybrid combination of SCC and Inductors, the so called Hybrid Switched Capacitor Converter (H-SCC), merges the benefits of both SMPS technologies, providing architectures not yet used in integrated converters and substantially improve the power density of PSoC and PSiP.

Bonding-wire triangular spiral inductor for on-chip switching power converters

This work presents the first design and modelling of bonding-wire-based triangular spiral inductors (Fig. 1), targeting their application to on-chip switching power converters. It is demonstrated that the equilateral triangular shape compared to other polygonal shapes best balances the inductive density as well as the total Equivalent Series Resistance (ESR). Afterwards, a design procedure is presented in order to optimize the inductor design, in terms of ESR and occupied area reduction. Finally, finite-elements simulation results of an optimized design (27 nH, 1 O) are presented to validate the proposed expressions
