An impulse radio ultra‐wideband (IR‐UWB) transmitter (TX) consuming ultra‐low power is presented. The low‐complexity topology features control of the power spectral density (PSD) and central frequency for a broad range of applications. The PSD and frequency adjustment are accomplished by employing a tunable pulse generator and an adjustable driver. The IR‐UWB TX suitable for on–off keying coding is fabricated in a low‐cost 180 nm UMC CMOS technology and occupies the total die area of 0.63 mm 2 . The measurement results show the transmitter output swing of 320 mVpp (peak‐to‐peak amplitude) with the pulse duration of 0.6 ns, and the spectrum covering the frequency range from 3 to 7.5 GHz. The total DC power consumption is 1 mW resulting in energy consumption of 5 pJ/pulse at 200 MHz data rate.
