Abstract   This work proposes a novel method to find the phase error and oscillation amplitude in multiphase LC oscillators. A mathematical approach is used to find the relationship between every stage's output phase and its coupling factor. To much more general analysis, every stage assumed to have a different coupling factor. The mismatches in LC tanks are considered as the main source of pha...

Techniques to overcome the errors caused by the offset, gain, and sample-time mismatches among timeinterleaved analog-to-digital converters (ADCs) in highspeed digital communication systems are presented. The errors introduced by these mismatches are adaptively corrected using digital signal processing blocks. Sampletime errors are corrected by modifying the operation of the existing adaptive r...

The time-interleaved analog-to-digital converter (TIADC) system could achieve high sampling rate effectively, but the frequency response inconsistency among channels will introduce mismatches, which seriously degrade signal quality. In this paper, a novel multi-channel mismatches adaptive calibration method is proposed. of compensation filter expanded into polynomial digital differentiator, and...
