A Signal Reconstruction Method for Time-interleaved ADC Converters

摘要

In this paper, a new reconstruction filter banks for correction signal is posed in order to compensate for the gain, phase and clock jitter of the sampling channel in time-interleaved analog-to-digital converters. The new filter banks can be computed the mismatches of gain, phase and clock jitter of the sampling channel, and update the filter coefficients in order to achieve perfect signal reconstruction. Finally, a four channel 14-bit 5GHz time-interleaved is implemented. The simulation results show that the proposed filter banks can improve the dynamic range of the sampled signal to reach 80 dB.
