CALIBRATING TIMING, GAIN AND BANDWITH MISMATCH IN INTERLEAVED ADCS USING INJECTION OF RANDOM PULSES |
摘要 |
A method and a corresponding device for calibrating an interleaved analog-to-digital converter (ADC) involve injecting a pulsed, substantially-random signal into a plurality of channels in the ADC. After the substantially-random signal is injected, a gain correlation value is determined for each channel, which value indicates a degree of correlation between the injected substantially-random signal and an output of the respective channel. The gain correlation values are then compared to determine a degree of mismatch between the channels. At least one of the channels is calibrated as a function of the determined degree of mismatch. |
