Abstract

This invention discloses a gallium oxide array detector output signal processing circuit. The circuit includes a multi-channel transimpedance amplifier circuit, a voltage conversion circuit, an output circuit, and a microcontroller control system. The detector socket is connected to the input terminal of the multi-channel transimpedance amplifier circuit, and the output terminal of the detector socket is connected to the input terminal of the multi-channel transimpedance amplifier circuit. When the gallium oxide array detector is in operation on the socket, it outputs a current signal to the multi-channel transimpedance amplifier circuit, which converts the current signal into a voltage signal and amplifies it. The output stage of the multi-channel transimpedance amplifier circuit is connected to the input stage of the voltage conversion circuit. The voltage conversion circuit is powered by a communication signal provided by the microcontroller, enabling it to convert the voltage signal into a digital signal that can be recognized by a computer or similar device. This invention, through the circuit design of the multi-channel transimpedance amplifier circuit, voltage conversion circuit, and output circuit, improves the range of signal amplification factors in the signal amplification system and its applicability to imaging systems.
