Abstract:
1. An ultra-wideband receiver comprising: a filter coupled to a signal input, the filter to pass signals in a frequency band from a received signal provided by the signal input; an amplifier coupled to the filter, the amplifier to bring the passed signals to a signal level compatible with circuitry in the receiver; a demodulating unit coupled to the amplifier, the demodulating unit containing circuitry to bring the passed signals to an internal frequency, thereby providing a demodulated signal at an output of the demodulating unit; a timing generating unit coupled to the demodulating unit, the timing generating unit containing circuitry to generate samples of the demodulated signal at different timing offsets, wherein the timing generating unit comprises a pair of sample/hold circuits having inputs coupled to the output of the demodulating unit, and wherein a first sample/hold circuit produces an on-time sample of the demodulated signal and a second sample/hold circuit produces an early and a late sample of the demodulated signal; and a converter coupled to the timing generating unit, the converter to convert continuous samples produced by the timing generating unit into discrete samples.
