Abstract:
1. An apparatus for equalizing a continuous-time signal comprising: a serial-to-parallel over-sampler configured to receive the continuous-time signal and output a first multi-bit data, and an equalizer, coupled to the serial-to-parallel over-sampler, configured to: receive the first multi-bit data; detect and remove a condition of bubble transition in the first multi-bit data to produce a modified multi-bit data, wherein a bubble transition is defined by more than two transitions within consecutive samples of a sample length that is proportional to an oversampling ratio of the serial-to-parallel over-sampler; establish a list of indices pointing to locations of data transitions in the modified multi-bit data; sequentially examine a respective run length of the data indexed by each entry in the list; modify associated data to lengthen the run length in response to a determination that the run length is too short and to shorten the run length in response to a determination that the run length is too long; and output a second multi-bit data.
