Abstract:
1. An electronic apparatus formed on a substrate, the electronic apparatus comprising: a first set of polysilicon fingers coupled to the substrate and configured to receive a first differential input signal; a first interconnect formed of a first metal layer and coupled to said first set of polysilicon fingers and having a first lengthwise axis; a second set of polysilicon fingers coupled to the substrate and interdigitated with the first set of polysilicon fingers, wherein the second set of polysilicon fingers is configured to receive a second differential input signal; and a second interconnect formed of a second metal layer that is a different layer from the first metal layer, the second interconnect being coupled to said second set of polysilicon fingers and having a second lengthwise axis, said second lengthwise axis parallel to said first lengthwise axis, and said first lengthwise axis different from said second lengthwise axis; a third interconnect coupled to said first interconnect and said first set of polysilicon fingers, said third interconnect having a third lengthwise axis that is perpendicular to said first lengthwise axis, wherein the third interconnect is formed of a different layer from the second metal layer; a fourth interconnect coupled to said second interconnect and said second set of polysilicon fingers, said fourth interconnect having a fourth lengthwise axis that is perpendicular to said second lengthwise axis; and an air bridge between said third interconnect and said second interconnect.
