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

“…In this paper, we extended our previous work [6], presenting practical results and emphasizing that this delay estimation method can estimate the timing mismatch in channels of a parallel AIC implementation. The proposed method uses a copy of the sensing functions of the AIC itself and, unlike the other methods, does not depend on reconstruction algorithms.…”

“…Independent of architecture, the physical implementations of AIC suffer from the components imperfections and noise interference due to circuit design and fabrication [3,4], like any device that employs mixed-signal technologies, mainly when off-the-shelf (OTS) components are used. These problems can cause, for example, gain and offset errors [5] and loss of synchronization between the input signal and the AIC control signals [6], which compromises the measurement and consequently the signal reconstruction quality. The application of a calibration process can overcome these problems improving the AIC performance.…”
