Resumé:
The Time interleaved ADC aims to get high speed converter using low speed ADC. It consists of M parallel channels. Each channel contains the low speed ADC. The channels operate with the same sampling frequency fclk but with different phases. The whole system sampling frequency fs equals to Mfclk. Mismatches between the channels used in the time interleaved ADC highly affect the performances of the system such as the signal to noise ratio thus the resolution of the ADC and the spurious free dynamic range. Three different type of mismatches can appear in this system; offset mismatch, gain mismatch and time skew mismatch.
Our objective is to implement calibration techniques to solve these problems and maintain the desired specification.
