초록/요약
An impulse radio ultra-wideband (IR-UWB) transceiver is implemented with low power, high data rate communication techniques, such as extended multipulse position modulation (E-MPPM), cross-coupled (CC) envelope detection, and digital frequency hopping (DFH). The use of the E-MPPM helps increase the modulation efficiency. The capacitive-CC technique helps improve the sensitivity by increasing the conversion gain of an envelope detector. DFH increases the pulse energy of a transmitted impulse without sacrificing the power spectral density (PSD) requirement. The proposed CMOS transceiver achieves a data rate of 1.125 Gbps and a radio range of 2 m with a power consumption of 28 mW and energy efficiency of 24.9 pJ/b. IEEE
