A data receiving and processing channel including analog signal processing circuitry operable for receiving data in the form of an input analog signal, and modifying the input signal in accordance with selected parameters so as to generate a modified analog input signal. According to one embodiment, there is provided a charge domain signal equalizer which initially transforms the modified analog input signal into a corresponding analog charge domain signal, the equalizer performing waveform shaping of the analog charge domain signal in accordance with a predetermined signal response template; a charge domain analog-to-digital converter operable for converting the analog charge domain signal into a corresponding digital signal; and a digital signal processor operable for recovering a digital bit stream from the digital signal which is indicative of the original data. In an alternative embodiment, there is provided an analog-to-digital converter operable for converting the modified analog input signal into a corresponding digital signal; a charge signal equalizer which initially transforms the digital signal into a corresponding digital charge signal, the equalizer performing waveform shaping of the digital charge signal in accordance with a predetermined signal response template; and a charge domain digital signal processor operable for recovering a digital bit stream from the digital charge domain signal which is indicative of the original data.
