Design of Signal Detector for Serial Data Transmission Receiver
During the data transmission of high speed serial IO,receiver should distinguish whether the valid data is transmitted across transmission line.Then,it changes the working mode according to results.Firstly,introduction of signal derector and traditional architectures are presented.After that,a signal detector is proposed based on high-speed rectifier utilizing current feedback,that can convert the amplitude of input signal to dc level and deter-mine the validity of input data.With the help of current feedback,the accuracy of rectifier can be improved by dynamic bias current when the amplitude of input signal is small.Therefore,the gain of pre-amp can be reduced to decrease the power comsumption of signal detector.
