  • Is a transimpedance amplifier a negative feedback amplifier

    Is a transimpedance amplifier a negative feedback amplifier

    The Transimpedance amplifier circuit is a simple Inverting amplifier with negative feedback. Along with the amplifier, a single feedback resistor (R1) is connected to the inverting end of the Amplifier as shown below. It is also achievable to design an active current to voltage converter with active components like. Transimpedance amplifiers (TIAs) act as front-end amplifiers for optical sensors such as photodiodes, converting the sensor's output current to a voltage. In a patent filed in. Considering there is current flow through R1, then there is a voltage across this resistor, so the output voltage will adjust itself in a way that the negative input pin is still zero, so how much this argument is correct? but still how can I justify the previous argument that I made? when there is.
