Analysis of mismatch noise in randomly interleaved ADC system

چکیده
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 sample instance. The periodicity of the errors is then removed and the spurious distortion is changed to a more noiselike distortion, spread over the whole spectrum. In this paper, a probabilistic model of the randomly interleaved ADC system is presented. The noise spectrum caused by gain errors is also analyzed.

To significantly increase the sampling rate of an A/D converter (ADC), a time interleaved ADC system is a good option. The drawback of a time interleaved ADC system is that the ADCs are not exactly identical due to errors in the manufacturing process. This means that time, gain and offset mismatch errors are introduced in the ADC system. These errors cause non harmonic distortion in the sampled...
متن کاملChannel linearity mismatch effects in time-interleaved ADC systems
A time-interleaved ADC system is an effective way to implement a high-sampling-rate ADC with relatively slow circuits. In the system, several channel ADCs operate at interleaved sampling times as if they were effectively a single ADC operating at a much higher sampling rate. Mismatches among channel ADCs degrade SNR and SFDR of the ADC system as a whole, and the effects of offset, gain and band...
متن کاملAnalysis, Estimation and Compensation of Mismatch Effects in A/D Converters
The trend in modern communication systems is to replace as much analog circuits as possible with digital ones, to decrease size, energy consumption and cost. An analog to digital converter (ADC) is the interface between the analog and digital parts. Replacing analog parts, such as mixers, with digital ones requires higher sampling rates. The bottleneck in a digital communication system is often...

Here in this paper we are presenting a digital system background technique for correcting the time, offset, error rate and gain mismatches in a time-interleaved analog-to-digital converter (ADC) system for N-channel communication using 8-bit ADC0808 IC’s. A time-interleaved A–D converter (ADC) system is an effective way to implement a high-sampling-rate ADC with relatively slow circuits. This p...
