Abstract:
A transimpedance amplifier with an input configured to receive a current input from an upstream device and output configured to present an output voltage. In one configuration, there are three amplifier stages in the transimpedance amplifier connected in series. A feedback path with feedback resistor connects between the input and output of the transimpedance amplifier. A bandwidth extender circuit connects between a stage output and a stage input of the transimpedance amplifier. In a three-stage embodiment, the bandwidth extender circuit extends between an input of the second stage and the output of the second stage. The bandwidth extender includes at least one active device configured to provide positive feedback to increase gain. The bandwidth extender circuit may be automatically or selectively deactivated to filter unwanted frequency components.

Claim (Index 12):
A method for processing an input current with a transimpedance amplifier to generate a corresponding amplified voltage comprising:\n receiving the input current at a first stage amplifier of the transimpedance amplifier, the transimpedance amplifier having one or more amplifier stages that includes a first stage amplifier; receiving a feedback signal from a feedback path at the first stage amplifier, the feedback path including feedback resistor; amplifying the feedback signal and the input current with the one or more amplifier stages to generate a transimpedance amplifier output signal; presenting the transimpedance amplifier output signal as an input to the feedback path; performing bandwidth enhancement by amplifying an amplifier stage output signal from one or more of the one or more amplifier stages and presenting the amplified amplifier stage output signal as positive feedback to an input of the one or more amplifier stages to increase the gain of at least one amplifier stage of one or more amplifier stages of the transimpedance amplifier to thereby increase the bandwidth of the transimpedance amplifier.
