Time-interleaved analog-to-digital converter (TI-ADC) technology can increase the sampling
rate without changing resolution. But, the dynamic performance of TI-ADC system is …

Time-interleaved analog-to-digital converters can significantly increase system sampling
rate, but channel mismatches, such as gain mismatch, offset mismatch and phase mismatch …

New linear models to calibrate four-channel time-interleaved analog-to-digital converters
are proposed and investigated. The ideal four-periodic correction filters, which cancel …

The most recent digitizers available on the market can grant real-time bandwidth up to 70
GHz and beyond. Such a performance is achieved by transforming the signal at the analog …

A new calibration technique for time-interleaved analog-to-digital converters is proposed,
based on Hermitianity-preserving complex Taylor approximations of the frequency response …

In this paper, we propose a pure digital blind calibration method to estimate and calibrate
offset, gain and timing mismatches. Gain errors are calibrated based on first channel …

Bandwidth mismatch is one of the mechanisms that reduce linearity in time-interleaved
analog-to-digital converters (TI-ADCs). Models of bandwidth mismatch have been already …

The paper presents the problem of design and simulation of a high-speed wide-band high-
resolution analog-to-digital (ADC) converter working in a bandpass scenario. Such …

We propose a novel recursive least squares (RLS) algorithm that exploits the Frisch-Waugh-
Lovell theorem to reduce digital complexity and improve convergence speed and …

One of the critical functions of a cognitive radar is to examine a large frequency spectrum in
real time, in order to detect the presence of narrowband emitters, which radiate on the same …
