Abstract
A symbol interference cancellation circuit may include a CTLE (continuous time linear equalizer) configured for cancelling a first post cursor component of an input signal according to a first weight application signal, and generating a pre-interference-cancelled signal; an interference cancellation circuit configured for cancelling second to fourth post cursor components of the pre-interference-cancelled signal according to second to fourth weight application signals, a sampling signal and output signals of shift registers, and generating an interference-cancelled signal; a sampling circuit configured for sampling the interference-cancelled signal based on a clock signal, and outputting the sampled interference-cancelled signal as the sampling signal; and the shift registers configured for shifting the sampling signal by a predetermined cycle of a clock bar signal which has a phase opposite to the clock signal, shifting the sampling signal by a predetermined cycle of the clock signal, and thereby providing shifted signals to the interference cancellation circuit.
