Abstract
A non-multiply-accumulate (non-MAC) charge-based analog correlator system including a sampler circuit block, an operand generation circuit block, and a margin propagation (MP) correlation computation circuit block is disclosed. The sampler circuit block is configured to sample a plurality of input analog signals. The operand generation circuit block is configured to generate operands based on the sampled plurality of input analog signals, and the margin propagation (MP) correlation computation circuit block is configured to generate correlated output signals based on the operands and using calculations in a charge domain.
