Abstract
We present a fully analog, multiplier-free, sampled-
domain RF correlator to achieve high energy e fficiency for
radar workloads. The RF correlator employs a split-source
follower architecture that leverages the margin propagation (MP)
computing paradigm in the sampled domain. As a proof of
concept, we implement a 256 × 256 fully analog cross correlator
in a 22 nm SOI-CMOS process. Large analog delays are realized
using a sampling-based approach, and the design incorporates a
compact, power and ar
