An apparatus is provided which comprises: a first circuitry to sample a first input signal to generate a first sampled signal, and to sample a second input signal to generate a second sampled signal, wherein the first input signal comprises data; a second circuitry to receive the first sampled signal and the second sampled signal, and to generate a first pair of differential signals; an offset cancellation circuitry to cancel or reduce an offset in the first pair of differential signals; and a latch to receive the first pair of differential signals subsequent to the cancellation or reduction of the offset, and to output a second pair of differential signals, wherein the second pair of differential signals is indicative of the data.
