Abstract
A differential signal detecting device includes a secondary amplifier; a front-end receiver and a final amplifier which are respectively connected to the secondary amplifier; and a signal outputter which is connected to the final amplifier. The front-end receiver receives two externally inputted channels of differential signals and an externally inputted reference threshold voltage, differentiates and transduces the two channels of differential signals. The secondary amplifier receives and amplifies the signals which are outputted by the front-end receiver, and outputs the signals amplified again. The final amplifier differentiates and amplifies the signals outputted by the secondary amplifier and outputs the two channels of differentiated signals. The signal outputter receives the two channels of differentiated signals which are outputted by the final amplifier and processes the two channels of differentiated signals with a logical conjunction before outputting.
