Abstract:
An analog data slicer circuit for slicing a differential input signal formed of first and second analog signals, comprising:a differential comparator having first and second input terminals for receiving respectively, via respective resistors, said first and second analog signals that are mutually differential signals based on data to which a given DSV (digital sum value) is given, said comparator comparing input voltages applied to said first and second input terminals and producing a two-valued digital output signal; a charge pump driven by said digital output signal from said differential comparator; a transconductance amplifier for supplying first and second output currents to said first and second input terminals, respectively, of said comparator, said first and second output currents being mutually differential signals proportional to a difference voltage between an output voltage from said charge pump and a reference voltage; and wherein said digital signal is controlled to achieve said given DSV.
