Claim:
1. A transimpedance amplifier comprising: a first and a second power supply terminal for receiving a positive constant supply voltage, wherein said second power supply terminal represents a ground; an input terminal configured to be electrically coupled to a current source, a first transistor including a control terminal and first and second conduction terminals, wherein said input terminal is electrically coupled to the control terminal of said first transistor; a first inductor electrically coupled between the first conduction terminal of said first transistor and said first power supply terminal; and a bias network electrically coupled between the second conduction terminal of said first transistor and the second power supply terminal; wherein said transimpedance amplifier has a resistance between said first conduction terminal of said first transistor and said first power supply terminal that is small enough to make said transimpedance amplifier operate as a differentiator.
