ABSTRACT:
The invention is to provide a receiving end architecture comprising a variable gain amplifier, for outputting a pair of differential signals comprising a first signal and a second signal via a first and a second outputs respectively according to the receiving signal through adjusting the amplitude of the receiving signal; a mix-type sample-and-hold circuit for outputting a first sampled signal via a first end and a second sampled signal via a second end and then outputting the second sampled signal via the first end and the first sampled signal via the second end through performing sample-and-hold on the pair of differential signals; and an analog/digital converter coupled to the mix-type sample-and-hold circuit for generating a digital signal according to the first and the second sampled signals.
