This brief discusses a mathematical steadystate model for fully-integrated boost and buck DC-DC converters, which takes all the significant resistive and dynamic power losses into account. The model provides a reduced calculation time by a factor 30 compared to SPICE. A 2%, or less, deviation in comparison with SPICE is achieved. The validation of the model through the measurements of both a fully-integrated boost and buck converter is demonstrated, resulting in an accuracy for the efficiency of 3 and 4% respectively.

Avionics industry is exploring new techniques to reduce cabling mass in modern aircrafts, leading to lighter and more fuel-efficient aircrafts. New trends are emerging towards the use of self-powered avionics sensors, which are simple to install, requires less maintenance and minimum wiring. A power harvesting circuit interface that uses avionics data lines for power harvesting was previously proposed. This interface can be coupled to an avionics sensor, making it self-powered without disturbing the ARINC 825 field bus. This paper presents a power conversion chain (PCC) module architecture and its circuit implementation required for the energy-harvesting interface. The proposed PCC design features a fast response time (5 msec settling time) and 60% power conversion efficiency. The PCC can be coupled to a compact power storage system consisting of super-capacitors. A 0.18 µm CMOS technology is used for circuit design, and simulations are carried out using Cadence.

“…To sum up, they provide low parasitic stray capacitances [11] and good inductive behavior in the frequency range above 1 GHz, but usually present low inductance value, and too high ESR. The application of bonding wires for inductors targeting on-chip CMOS switching power conversion has been independently proposed in [12] and in [13], in which for the latter an experimental prototype is validated. This work elaborates [12] to assess the potentially optimized performance of a triangular shape structure.…”

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 (27nH, 1 Ω) are presented to validate the proposed expressionsPeer ReviewedPostprint (published version
