1. A transimpedance amplifier comprising:
a resistor assembly coupled between an output of the transimpedance amplifier and an input of the transimpedance amplifier, the resistor assembly comprising:
a resistor having a longitudinal length, the resistor comprising:
a resistive element; andan insulator surrounding the resistive element; anda plurality of conductive compensation elements each at least partially surrounding the insulator along at least part of the longitudinal length of the resistor; and a voltage source for applying a first voltage to a first conductive compensation element of the plurality of conductive compensation elements and a second voltage to a second conductive compensation element of the plurality of conductive compensation elements, wherein:
the first voltage and the second voltage are each derived from the output voltage, Vout, of the transimpedance amplifier, the first voltage being a first proportion of Vout and the second voltage being a second proportion of Vout and wherein the voltage source comprises:a voltage controller for adjusting at least one of the first proportion and/or the second proportion. |
