Abstract :
The single analog filter (SAF) hybrid filter bank (HFB) ADC is presented in this paper. Base on SAF architecture, a calibration model is derived to integrate the analog filter´s realization errors and channel mismatches errors. A two-channel SAF HFB ADC with 12-bit resolution and 200MHz sampling rate is implemented. The experimental results show that the average spurious-free dynamic range (SFDR) over the whole frequency spectrum enhanced from 35 dB to 88.3 dB when the proposed calibration method has been used.
