- Abstract:
- This paper describes a technique mitigating the impact of timing mismatches in timeinterleaved analog-to-digital converters (ADCs). The systems signal-to-noise and distortion ratio (SINAD) and spurious-free dynamic range (SFDR) are increased by controlling the selection order of the channels ADCs in combination with oversampling and consecutive filtering. The proposed method requires only knowledge of the relative level of timing mismatch between the channel ADCs though not the precise magnitude of the mismatch. The impact of timing mismatch on the SINAD and advanced selection ordering schemes are discussed. Moreover, simulation results are presented comparing the figures of merit of existing techniques.
