Abstract:

In this paper we introduce an area efficient time-interleaved charge-injection-cell SAR ADC. The prototype TI-ADC interleaves 8 CIC SAR channels for a sampling rate of 6Gs/s and a compact area of 0.0060Smm2. A neural network calibration algorithm corrects multiple error sources in the time-interleaved ADC. The neural calibration method effectively improves the average measured ENOB of the TI-ADC from 4.1 bits to 5.49 bits.
