  • Patent number: 5942951
    Abstract: In a high current, high frequency integrated circuit chip characteristic of producing an excess of internal on-chip circuit induced noise with respect to a low current, low frequency circuit implemented on the high current, high frequency integrated circuit chip, a method is disclosed for reducing noise in the low current, low frequency circuit. The method includes placing noise sensitive components of the low current, low frequency circuit external to the integrated circuit chip, corresponding to an off-chip placement. An exclusive power supply reference line V.sub.(REF) tapped off of a power supply bus internal to the integrated circuit chip is provided. The exclusive power supply reference line V.sub.(REF) is tapped off the internal power supply bus on-chip at a physical location proximate the low current, low frequency circuit and routed off-chip. The noise sensitive components are connected between the low current, low frequency circuit and the power supply reference line V.sub.
