| Popis: | A 4×11-bit 1 GS/s 40 mW Collaborative ADC in 65nm CMOS is presented for a 4-Ch MIMO receiver. It utilizes the correlation information between channels to perform energy efficient digitization of received signals. By utilizing 8 SAR units each with 6-bit level of resolution, four level of ADC resolutions (11, 9, 6, and 6-bit), is achieved dynamically for optimal performance. This collaborative ADC in compare to all-11 and all-9 bit has an area and power reduction of 50% and 41% respectively with only 10% degradation in overall SNDR. |
