A method for delay estimation between channels of Analog to Information Converters

Analog to Information Converters (AIC) implements signal acquisition in Compressed Sensing. AIC performance is affected by noise and hardware imperfections. In parallel Random Modulator Pre-Integrator (RMPI) architectures, delay among channels reduces the performance; thus, estimation compensation methods are necessary. previous works, compares a reference with reconstructed from output; however, such produce different results according recovery method. To avoid this problem, we present method based on controlled estimate channel without necessity of recovery. The obtained show technique's feasibility possibility its use as built-in calibration process for AIC.
