Publication number: 20230299784Abstract: Described herein are techniques for mitigating bandwidth mismatch in time-interleaved (TI) analog-to-digital converters (ADC). The techniques described herein involve spreading the energy associated with spurious tones resulting from bandwidth mismatch across the frequency spectrum, thereby reducing the overall impact of each individual tone. In some embodiments, for example, the tones may disappear under the noise floor. Spreading the energy associated with the spurious tones can be achieved by increasing the periodicity of the phase oscillation. This, in turn, can be achieved by introducing, in the phase oscillation, artificial phase shifts in addition to the phase shifts arising due to bandwidth mismatch. In one example, increasing the periodicity of a phase oscillation from 4 phase samples to 8 phase samples can result in a reduction in the power of a tone as high as 7 dB.Type: ApplicationFiled: November 7, 2022Publication date: September 21, 2023Applicant: Media Tek Inc.Inventor: Gabriele Manganaro
