Patent ID: 8212611

Claim:
An apparatus comprising: a first transistor having a control electrode formed over a substrate, a first conduction region formed in the substrate, and a second conduction region formed in the substrate; a second transistor having a control electrode formed over the substrate, a first conduction region formed in the substrate, and a second conduction region formed in the substrate; a third transistor having a control electrode formed over the substrate, a first conduction region formed in the substrate, and a second conduction region formed in the substrate; a fourth transistor having a control electrode formed over the substrate, a first conduction region formed in the substrate, and a second conduction region formed in the substrate; a first portion of a first metallization layer formed over the substrate that carries a first portion of a differential local oscillator signal, wherein the first portion of the first metallization layer is coupled to the gates electrodes of the first and second transistors; a second portion of a first metallization layer formed over the substrate that carries a second portion of the differential local oscillator signal, wherein the first portion of the first metallization layer is coupled to the gates electrodes of the third and fourth transistors, wherein the first and second portions of the separated from one another; a first portion of a second metallization that is formed over the substrate, wherein the first portion of the second metallization layer is coupled to the first conduction regions of the first and fourth transistors; and a second portion of the second metallization layer that is formed over the substrate, wherein the second portion of the second metallization layer is coupled to the first conduction regions of the second and third transistors, and wherein one of the first and second portions of the second metallization layer includes a jumper so as to enable the first and second portions of the second metallization layer to cross.
