1. A receiver comprising:
N analog samplers each coupled to a common node to sample a continuous-time signal conveyed at a symbol rate, thereby providing N series of analog samples each conveyed at a sample rate lower than the symbol rate; and
for each of the N analog samplers:
a discrete-time amplifier coupled to an output of the analog sampler to amplify the respective series of analog samples, thereby providing an amplified series of analog samples; and
a quantizer coupled to an output of the discrete-time amplifier to quantize the respective amplified series of analog samples.
