The invention discloses photoelectric microelectronic signal compensation equipment, which comprises a buffer input module and a buffer comparison module, and the buffer input module receives an analog signal before modulation in a signal emitter of the photoelectric microelectronic equipment and is connected with the buffer comparison module; a 3.3 V alternating current power supply is directly compensated to the output end of an operational amplifier AR1 after direct current shunt is filtered by the capacitor C1, the buffer comparison module uses an operational amplifier AR3, a diode D3 anda diode D4 to form a peak circuit to be input into the inverting input end of an operational amplifier AR4, and the operational amplifier AR4 performs differential adjustment on positive signals in output signals and main signals of the peak circuit. And finally, the operational amplifier AR6, a resistor R13 and a resistor R14 form an addition circuit to add the signals again, and the phase difference between the positive signal and the negative signal is 180 degrees, so that the operational amplifier AR6 outputs a complete waveform signal, the phase offset is calibrated on the basis of a compensation signal, and meanwhile, the signal transmission quality is improved.
Description
technical field [0001] The invention relates to the technical field of signal compensation, in particular to an optoelectronic microelectronic signal compensation device. Background technique [0002] At present, microelectronic equipment is also photoelectric information equipment. The science of optoelectronic technology is the pillar and foundation of the optoelectronic information industry. Capacitive compensator is often used for the transmission of the signal, which provides stable compensation for signal transmission, but due to the hysteresis of the capacitor itself, the compensated signal waveform will have a certain phase shift compared with the source signal, thereby reducing the signal quality. Seriously affect the effect of microelectronic signal transmission. Contents of the invention [0003] In view of the above situation, in order to overcome the defects of the prior art, the object of the present invention is to provide an optoelectronic microelectronic ...
