A frequency-interleaving-based multichannel analogue-to-digitial converter (ADC) with mismatch compensation is presented, which is immune from the time skew problem that exist in the time-interleaved ADC. The channel mismatches, such as bandwidth mismatch, gain mismatch, offset mismatch and filter bank mismatch, are addressed and modelled in the reconstruction optimisation. A prototype of a four-channel 1 GS/s 12 bit frequency-interleaved ADC (FI-ADC) is designed to demonstrate the mismatch compensation. Simulation results show that the mismatches in the FI-ADC can be compensated effectively.
