- Abstract
A new methodology for sparse signal acquisition using a multi-comparator- based integrate-and-fire sampler is presented. By employing the randomness of comparator voltages, the original analogue signal is converted into a series of binaries and is guaranteed to be precisely recovered from these measurements. The proposed scheme operates with a sub-Nyquist rate, which requires neither a high-speed linear feedback shift register nor an accurate analogue-to-digital converter. The experimental results demonstrate the effectiveness of the proposed scheme.
