A fully integrated 3 ∼ 5GHz CMOS RF transceiver for IR-UWB applications is implemented in 0.18µm CMOS technology. The integrated RF notch filter is employed to reject the nearby WiFi and WCDMA interferers. The low power digital impulse generator is used as the UWB RF transmitter. The measured sensitivity of the receiver is −65dBm at 4GHz with 1Mbps PRF. And the measured energy efficiency per pulse is 20.6pJ/bit. The current consumption of the receiver and transmitter including DA is 27.5mA and 25.5mA, respectively, at 1.8V supply.
