A Novel Iterative Structure for Online Calibration of $M$-channel Time-Interleaved ADCs
This paper proposes a computationally efficient calibration structure for online estimation and compensation of offset, gain and frequency response mismatches in M-channel time-interleaved (TI) analog-to-digital converters (ADCs). The basic idea of the proposed approach is to reserve some sampling instants for estimating and tracking the mismatch parameters of sub-ADCs with reference to a known...
متن کاملA Signal Processing View on Time-Interleaved ADCS
The idea of time-interleaved ADCs (TI-ADCs) is old, but it took more than 25 years until the requirements on converters and the possibility of advanced digital post correction made this architecture attractive. We investigate timeinterleaved ADCs with a focus on the involved signal processing. By establishing a discrete-time model of a TI-ADC, we explicitly show that a TI-ADC with mismatches is...
متن کاملEFFICIENT RECONSTRUCTION OF TWO-PERIODIC NONUNIFORMLY SAMPLED SIGNALS APPLICABLE TO TIME-INTERLEAVED ADCs
Nonuniform sampling occurs in many practical applications either intentionally or unintentionally. This thesis deals with the reconstruction of two-periodic nonuniform signals which is of great importance in two-channel timeinterleaved analog-to-digital converters. In a two-channel time-interleaved ADC, aperture delay mismatch between the channels gives rise to a two-periodic nonuniform samplin...
متن کاملComprehensive Error Analysis of Combined Channel Mismatch Effects in Time-Interleaved ADCs
A)str.el A rinte-interlroved analog-tdigital convener (ADC) achieves high sampling rates with fhe drawback of additional distortions caused by ehsnnelmismntches. I n thispoper we consider fhe dependency of the signalfo-noise-nnd-aiFrortion ratio (SINAD) on all of these mismatch effecrs together. By using eilher explieifly given mismatch parameters or given paramaer distributions we derive close...
متن کاملModeling, Identification, and Compensation of Channel Mismatch Errors in Time-Interleaved ADCs
Modern signal processing applications emerging in telecommunication and instrumentation industries need high-speed analog-to-digital converters (ADCs), which can be achieved by employing a time-interleaved parallel array of ADCs (time-interleaved ADCs). The time interleaving of the channels allows to increase the sampling rate by the number of channels compared to a single channel. Unfortunatel...
