Patent ID: 8134188

Claim:
A transistor circuit, wherein the transistor circuit comprises: a transistor pair, the transistor pair including: a first transistor including: a first drain having a first side and a second side; a first source having a third side and a fourth side, wherein the first side is closer to the third side than to the fourth side, wherein the first side is closer to the third side than the second side is to the third side; and a first channel extending between the first drain and the first source, wherein a cross-sectional width of the first channel at the third side of the first source is substantially less than a cross-sectional width of the first channel at the first side of the first drain, wherein the first drain is the closest drain disposed over the first channel to the third side, wherein a gate extends continuously from one lateral side of the gate to another lateral side of the gate, the gate extending across the first channel such that a cross-sectional width of the first channel at the one lateral side is greater than the cross-sectional width of the first channel at the other lateral side; a second transistor including: a second drain and a second source, wherein a second channel extends between the second drain and the second source, wherein a cross-sectional width of the second channel near the second source is less than a cross-sectional width of the second channel near the second drain, wherein the second drain includes a fifth side and a sixth side, wherein the second source includes a seventh side and an eighth side; wherein the fifth side is closer to the seventh side than to the eighth side; wherein the fifth side is closer to the seventh side than the sixth side is to the seventh side; wherein the second drain is the closest drain to the third side; wherein the second channel varies in cross-sectional width from the seventh side of the second source to the fifth side of the second drain.
