Claim:
1. A circuit manufactured in an integrated form comprising trans-impedance amplifier circuitry, the trans-impedance amplifier circuitry comprising: an amplifier; a feedback resistor, wherein the feedback resistor is provided within the integrated form circuit as a strip with the width of the strip parallel to a substrate and the height of the strip perpendicular to the substrate of the integrated form circuit and arranged between an output of the amplifier and an input of the amplifier; a first further resistor, wherein the first further resistor is provided within the integrated form circuit as a strip with the width of the first further resistor strip parallel to a substrate and the height of the first further resistor strip perpendicular to the substrate of the integrated form and is arranged within the integrated form circuit to be physically parallel to the feedback resistor, the first further resistor is further arranged within the integrated form circuit to a first side of the feedback resistor; and a second further resistor, wherein the second further resistor is provided within the integrated form circuit as a strip with the width of the second further resistor strip parallel to a substrate and the height of the second further resistor strip perpendicular to the substrate of the integrated form and is arranged within the integrated form circuit to be physically parallel to the feedback resistor, and wherein the second further resistor is further arranged within the integrated form circuit to a second side of the feedback resistor, wherein the first and second sides are on opposed sides of said feedback resistor within the integrated form circuit, wherein at least one of the feedback resistor, the first further resistor, and the second further resistor is elongate.
