Method and device for analogue to digital conversion

摘要

A parallel SC ADC (switched capacitor analog-to-digital converter) includes a passive sampling technique controlled by a global clock phase to reduce the influence of the sampling phase skew. Since it does not require operational amplifiers for sampling, it is very suitable for high speed applications, and yet it can reduce the sampling-phase-skew-related distortion by 20-40 dB in a high speed, parallel SC ADC.
