Single-ended differential transimpedance amplifier

A differential amplifier comprising:

• a first current transfer system to generate a first differential current signal in response to a first current signal;
• a second current transfer system to generate a second differential current signal in response to a second current signal;
• a current difference producing system to receive the first differential current signal and the second differential current signal and to generate a voltage difference signal that is indicative of a difference between the first current signal and the second current signal;
• and
• a feedback network circuit to:
• convert the voltage difference signal into at least two converted current signals;
• and
• provide the at least two converted current signals to one of the first and second current transfer systems or the current difference producing system to minimize the difference between the first current signal and the second current signal based on the at least two converted current signals.

A method for minimizing current between a first current and a second current, the method comprising:

• providing a first current signal and a second current signal;
• generating a first differential current signal via a first current transfer system in response to the first current signal;
• generating a second differential current signal via a second current transfer system in response to the second current signal;
• receiving the first differential current signal and the second differential current signal at a current difference producing system;
• providing a voltage difference signal that is indicative of a difference between first current signal and the second current signal;
• converting the voltage difference signal into at least two converted current signals;
• and
• providing the at least two converted current signals to one of the first and second current transfer systems or the current difference producing system to minimize the difference between the first current signal and the second current signal based on the at least two converted current signals.
