Abstract (in Japanese) (See Japanese page) 
(in English) A new adaptive background calibration for gain mismatches and sample-time mismatches in a Time-Interleaved Analog-to-Digital Converter (TI-ADC) is presented. The proposed technique using a pseudo aliasing signal can greatly reduce the hardware. The pseudo aliasing generator consists of the
Hadamard transform and a fixed FIR filter. The requirement for the word length of the FIR filter can be reduced about 50% without look-up table (LUT) compared with a conventional compensation filter. In addition, the proposed technique requires only one FIR filter for mismatch compensation compared with the conventional technique which require (M-1) FIR filters in an M-channel TI-ADC
