ABSTRACT:
An electronic device (10) comprises a copper integrated inductor (11) overlying other solid state components (31) of the device (10). Preferably, the copper inductor (11) is formed of plated copper to a thickness of several microns. The preferred integrated inductor (11) provides significant advantage over external inductors of the past with respect to simplicity of manufacture as well as system size and cost. Additionally, the preferred inductor (11) provides improved inductance per area, lower series resistance and higher Q values, relative to inductors of the past.
