چکیده

We introduce a behavioral MATLAB simulation of a time-interleaved ADC. The simulation includes the main error sources of a time-interleaved ADC and works with continuous-time input signals and continuous-time input filters. We clarify how to implement the signal generation and how to connect the continuous-time and the discrete-time part of the time-interleaved ADC with high calculation precision. By using the simulation results, we treat the problem of channel mismatches, demonstrate the problems of bandwidth mismatches, and show the impact of nonlinearities.

Modeling, 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...

Analysis of Mismatch Noise in Randomly Interleaved ADC System, Report no. 2487

Time interleaved A/D converters (ADCs) can be used to increase the sample rate of an ADC system. However, a problem with time interleaved ADCs is that distortion is introduced in the output signal due to various mismatch errors between the ADCs. One way to decrease the impact of the mismatch errors is to introduce additional ADCs in the interleaved structure and randomly select an ADC at each s...

A 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...

An Analysis of Time Interleaved-ADC through Literature Review

In this research survey work we have presented the performance analysis of TI-ADC in order to enhance the performance it is very important to prepare a survey so we have done through a literature survey. In many mix-signal systems, analog-to-digital converters (ADCs) play an important role for digitizing analog signal. To design high-speed and high-resolution ADCs, multichannel ADC structure is...
