An ultralow-power and low-complexity impulse radio ultrawideband (IR-UWB) transmitter (TX) is fabricated in the low-cost 180-nm United Microelectronics Corporation (UMC) CMOS technology. The TX offers control of the power spectral density (PSD) by using a tunable pulse generator and a controllable switched oscillator. It supports on-off keying (OOK) coding and occupies a total die area of 0.35 mm 2 . The measured results show the transmitter output amplitude of 130 mVp-p with the pulse width of 1.0 ns, and the PSD with 10-dB bandwidth from 3 to 8.8 GHz. The total dc power consumption is 0.6 mW, corresponding to the energy consumption of 3 pJ/pulse at 200-MHz pulse repetition frequency.
