Other AbstractThe utility model belongs to an amplifying technique, more specifically a PSD photoelectric signal ultimate amplifier. The utility model is composed of an operational amplifier, a first to a fifth resistors, and a first and a second capacitors, wherein the negative input end of the operational amplifier is connected with the first capacitor and the second resistor to form an operational amplifier signal passage to connect to the ground via the first resistor, and the output end has six feet. An amplified feedback loop of the operational amplifier is formed by the second capacitor and the third resistor, and is connected with the feedback end of the operational amplifier. The fourth and the fifth resistors are respectively connected with the positive input end of the operational amplifier and the reference voltage end so as to regulate the stability of the amplifier. The utility model is an alternating-current small-signal ultimate amplifier which can furthest utilize the magnifying performance of the operational amplifier and has excellent restraining effect to noise.
