Abstract :
The frequency-translating hybrid analog-to-digital converter (FTH-ADC) architecture is based on frequency interleaving and decomposing the wideband analog input signal into narrower-bandwidth analog baseband subbands, digitizing them, and performing further signal processing in the digital domain. In this paper, digital compensation techniques to enhance the performance of the FTH-ADC system in the presence of errors due to a variety of mismatches are presented. The effectiveness of these techniques to enhance the performance of the system is confirmed using a proof-of-concept two-channel prototype.
