Abstract
A broadband digitizer for an applied broadband analog input signal SA(t). The digitizer includes a low frequency analog-to-digital converter (LF ADC) channel and a high frequency analog-to-digital converter (HF ADC) channel, an input splitter coupled to respective inputs to the LF ADC channel HF ADC channels, a frequency divider, and a combining unit. Low frequency portions of SA(t) are digitized to digital signal SD[n] in the LF ADC channel and high frequency portions of SA(t) are digitized to digital signal SD[n] in the HF ADC channel. The combining unit combines the digital signals SD[n] and SD[n] to form distortion-reduced SD[n], corresponding to SA(t). Front ends of the LF ADC channel and HF ADC channel reduce level-caused distortions, and the combining unit reduces ADC frequency-caused, time-position-caused, and interpolation-caused distortions.
