Transimpedance amplifier with low supply voltage

A circuitry, comprising:

• a transimpedance amplifier stage, configured to receive a current signal to generate an output voltage signal, wherein the transimpedance amplifier comprises:
• a first transistor having a gate electrode, a first electrode and a second electrode, wherein the gate electrode of the first transistor is coupled to the current signal, and the first electrode of the first transistor is coupled to a supply voltage;
• a second transistor having a gate electrode, a first electrode and a second electrode, wherein the first electrode of the second transistor is coupled to the second electrode of the first transistor, and the second electrode of the second transistor is coupled to a ground voltage;
• a feedback resistor, coupled between an output terminal and an input terminal of the transimpedance amplifier stage, wherein the output terminal is a node between the second electrode of the first transistor and the first electrode of the second transistor;
• and
• a high-pass filter, configured to filter the current signal to generate a filtered current signal to the gate electrode of the second transistor.
