Abstract
Time-division quadrature sampling may be used in a pulse-modulated continuous wave (PMCW) radar receiver circuit, e.g., as may be employed in various types of radar sensors used in automotive and other applications, to enable a quadrature sampling circuit to sequence between digitally sampling different complex components of a received radar signal at different times.
