Abstract :
This paper presents a low complexity 1-bit pseudorandom number generator used in a digital background calibration for ADCs. The pseudorandom sequence generator is based on a chain of accumulators, with time-varied coefficients, that obtain a 1-bit sequence with good statistical properties. Behavioral simulations show that the convergence on the compensation algorithm in ADCs is improved.
