Comparator, decision feedback equalizer, receiver, interface circuit and electronic equipment

Abstract

The invention relates to the technical field of computers, in particular to a comparator, a decision feedback equalizer, a receiver, an interface circuit and electronic equipment. The comparator provided by the embodiment of the invention comprises a signal input module, a latch and an acceleration starting module. The signal input module comprises a first signal input unit and a second signal input unit, the first signal input unit is used for being connected to a first signal receiving end and connected with a first starting control end of the latch through a first signal input line, and thesecond signal input unit is used for being connected to a second signal receiving end, and connected with the second starting control end of the latch through a second signal input line, the acceleration starting module comprises a first acceleration starting unit and a second acceleration starting unit, the first acceleration starting unit is connected with the first signal input line, and the second acceleration starting unit is connected with the second signal input line. According to the comparator provided by the embodiment of the invention, the starting working duration of the latch canbe reduced, and finally, the time delay of the comparator is reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a comparator, a decision feedback equalizer, a receiver, an interface circuit and electronic equipment. Background technique [0002] With the continuous increase of the interface circuit bandwidth, the receiver needs to work at a higher frequency, and at the same time, it needs to deal with greater signal attenuation and interference. Therefore, the design of the receiver becomes the bottleneck of the design of the high-speed interface circuit. At present, in order to receive a weaker input signal and at the same time, in order to deal with greater intersymbol interference, the receiver will use a decision feedback equalizer to compensate for the intersymbol interference of the input data signal, and the comparator is the core of the feedback equalizer Module, the comparator is used to judge the analog signal and convert the analog signal into a digital signal. Sinc...

AI Technical Summary

Problems solved by technology

It can be understood that, in the prior art, no matter which way the comparator controls the start-up of the latch during the working process, since the process takes a long time, the duration of the start-up of the latch is increased. Ultimately, increasing the delay of the comparator
