Abstract
In a receiver facility in an ultra-wideband communication system, a dual-mode circuit adapted to operate in a selected one of three operating modes without changes in circuit topology: a calibration mode adapted to render the circuit substantially independent of circuit component mismatches; a frequency comparator mode adapted to indicate whether the frequency of a first periodic signal is larger or smaller than the frequency of a second periodic signal; and an early-late detector mode adapted to indicate whether the 1rising edge of the first periodic signal arrived sooner or later than the 1rising edge of the second periodic signal applied.
