Abstract

In this paper, a new technique, the Multiple-Phase Capacitor-Splitting Feedback Interchange (MP-CSFI) technique, is presented to reduce the harmonic distortion due to capacitor mismatch for pipelined ADCs. The basic idea is to split the capacitors in the sub-DACs of a pipelined ADC and dynamically select subsets of the split capacitors as the feedback ones during its operation such that the non-ideal effects caused by capacitors' mismatches can be disturbed and modulated to higher frequency band. A 12-bit, 35MHz pipelined A/D converter with the proposed technique is designed and simulated using the TSMC 0.25 μm 1P5M technology to demonstrate the effectiveness of this technique.
