Abstract: Time-Interleaved Analog-to-Digital Conversion(TIADC) is one of the most important techniques in the design of high-speed waveform digitization systems, it can multiple the sampling rate of a sampling system. However, there are mismatch errors between different sampling channels, which will make the dynamic performance of a TIADC system significantly lower than that of a single ADC. Therefore, mismatch errors should be corrected in TIADC system design. To evaluate the quality of the system design and promote the next optimization design, it is necessary to conduct scientific performance test and evaluation on the TIADC system. In this work, aiming at the test and evaluation, the performance indexes and test methods of TIADC system are introduced in detail, a series of performance tests of the system are completed, and mismatch errors are corrected based on perfect reconstruction algorithm. The test results show that the system can achieve an equivalent 5 Gsps sampling rate and can realize mismatch error correction in a wide band based on the proposed mismatch error correction method. After correction, the dynamic performance of the TIADC system is significantly enhanced compared with that without correction. For example, the Effective Number of Bits(ENOB) of the proposed system reaches 9.2 bits at 247 MHz, 8.9 bits at 857 MHz, which is equivalent to the performance index of a single ADC.
