Abstract

This paper presents the design of a 1 : 50 bondwire micro-transformer assembled with IC gold bonding wires and a toroidal LTCC magnetic core with race-track shape. The transformer is fabricated on-top of a standard BCD IC in a 15 mm(2) footprint area for micro-power energy harvesting applications. Measurements show a secondary self-inductance up to 29 mu H with a maximum Q-factor of 11.6 at 1.3 MHz, and a coupling coefficient of 0.65 with an effective turns ratio of 19. This miniaturized technology finds also applications in power supply in package (PwrSiP) and power supply on chip (PwrSoC). (C) 2014 The Authors. Published by Elsevier Ltd.
