Abstract:
A multi-stage transimpedance amplifier (TIA) which includes a common gate amplifier configured to receive a current signal, the common gate amplifier is configured to convert the current signal into an amplified voltage signal. The multi-stage TIA further includes a capacitive degeneration amplifier configured to receive the amplified voltage signal, the capacitive degeneration amplifier is configured to equalize the amplified voltage signal to form an equalized signal. The multi-stage TIA further includes an inverter configured to receive the equalized signal, the inverter is configured to increase a signal strength of the equalized signal to form an output signal. The multi-stage TIA further includes a feedback configured to receive the output signal, wherein the feedback is connected to an input and an output of the inverter.
