In this paper, a new in-package high efficiency voltage down converter (VDC) is presented. Usually, quality factor of inductors is the main problem for generating high efficiency DC-DC Converters. In order to mitigate this problem, Bonding Wires with a new form are exploited in which four mutual inductions of bonding wire are used to increase the total inductance. This technique provides a high quality and low space in-package inductor with negligible parasitic elements. The peak efficiency for the proposed circuit at 50MHz switching frequency is around 86% with 150mA loading current.
