Abstract:
This work proposes a rapid digital amplification (RDA) with residue-aware reference, offering an equivalent open-loop (OL) gain enhancement of 25 dB and reducing the interstage gain error (ISGE)-induced SNR degradation by 20 dB, with an extra amplification latency of only 200 ps. It is implemented in an 800-MS/s 13-b two-way time-interleaved (…
