The proposed designs eliminate the requirement of complex synchronisation circuit architectures and algorithms. The presented circuits are all digital and can be utilised in the baseband synchronisation. The digital envelope detection and self-correlation methods are implemented in 130 nm complementary metal oxide semiconductor (CMOS) technology and concepts are verified with measurement results. Post-layout simulation results are given for the high frequency sampling technique. Measurements show that the digital envelope detector demonstrates successful operation up to 600 Mbps data rate with 2.1 mW power consumption. The self-correlator consumes 10 mW with 100 Mbps data rate in the measurements. The post-layout simulations results show that the high frequency sampler can operate at 2 mW with 500 Mbps data rate.eninfo:eu-repo/semantics/closedAccessRadio ReceiversUltra Wideband CommunicationCmos İntegrated CircuitsDemodulationAmplitude Shift KeyingCorrelation MethodsDigital Envelope Detectionİmpulse Radio Ultra-Wideband ReceiversComplex Synchronisation Circuit ArchitecturesBaseband SynchronisationSelf-Correlation MethodsPost-Layout Simulation ResultsDigital Envelope DetectorHigh Frequency SamplerFrequency SamplingData Rate DemodulationNoncoherent On-Off Keying DemodulationCmos TechnologyClockArticle2-s2.0-8507316858910.1049/iet-cds.2018.54588476Q384313Q4WOS:000537293500015
