Abstract
An apparatus includes a transimpedance amplifier having at least one input and an output. The apparatus also includes an adaptive input current variation circuit connected to the at least one input of the transimpedance amplifier and configured to receive at least one input current and adjust the at least one input current to a selected input current provided to the at least one input of the transimpedance amplifier.
Claims20
An apparatus comprising:
- a transimpedance amplifier having at least one input and an output;
- and
- an adaptive input current variation circuit connected to the at least one input of the transimpedance amplifier and configured to receive at least one input current and adjust the at least one input current to a selected input current provided to the at least one input of the transimpedance amplifier.
An apparatus comprising:
- a transimpedance amplifier having at least one input and an output;
- and
- an adaptive input current variation circuit connected to the at least one input of the transimpedance amplifier and configured to receive at least one input current and adjust the at least one input current to a selected input current provided to the at least one input of the transimpedance amplifier, wherein the adaptive input current variation circuit is further configured to drain an input DC current from the at least one input current.
A method for operating a transimpedance amplifier, the method comprising:
- receiving at least one input current;
- adjusting the at least one input current to a selected input current that is provided to at least one input of the transimpedance amplifier using an adaptive input current variation circuit;
- and
- outputting an output voltage from the output of the transimpedance amplifier responsive to the at least one input current.
