An Adaptive Synthesis Calibration Method for Time-Interleaved Sampling Systems

An Adaptive Synthesis Calibration Method for Time- Interleaved Sampling Systems

In a parallel time-interleaved data sampling system, timing and amplitude mismatches of this structure degrade the performance of the whole ADC system. In this paper, an adaptive blind synthesis calibration algorithm is proposed, which could estimate the timing, gain and offset errors simultaneously, and calibrate automatically. With no need of an extra calibration signal and redesign, it could...

AN ADAPTIVE IMPORTANCE SAMPLING-BASED ALGORITHM USING THE FIRST-ORDER METHOD FOR STRUCTURAL RELIABILITY

Monte Carlo simulation (MCS) is a useful tool for computation of probability of failure in reliability analysis. However, the large number of samples, often required for acceptable accuracy, makes it time-consuming. Importance sampling is a method on the basis of MCS which has been proposed to reduce the computational time of MCS. In this paper, a new adaptive importance sampling-based algorith...

Photoconductive-Sampling Time-Interleaved CMOS ADC

High speed analog-to-digital converters capable of digitizing signals with bandwidths of several tens of GHz have applications in high-speed instrumentation, wideband radar and optical communications. However, the design of converters with such high input bandwidths is constrained by the need for wideband sample-and-hold circuits with sufficiently low clock jitter. A number of photonic sampling...
