Claim:
1. An apparatus, comprising: a first injection transistor comprising a first source; a second injection transistor comprising a second source, wherein the first injection transistor and the second injection transistor are cross coupled, and wherein the first source and the second source are connected to a first ground; a first symmetry injection transistor comprising a third source; a second symmetry injection transistor comprising a fourth source, wherein the third source and the fourth source are connected to a second ground, wherein the first symmetry injection transistor, the second symmetry injection transistor, the first injection transistor, and the second injection transistor are formed on a single transistor cell, and wherein a transistor width of a transistor of at least one of the first symmetry injection transistor, the second symmetry injection transistor, the first injection transistor, or the second injection transistor varies from that of another transistor width of a different transistor of the at least one of the first symmetry injection transistor, the second symmetry injection transistor, the first injection transistor, or the second injection transistor; a first node comprising: a second node comprising: a third node comprising:
