A 6–9GHz WiMedia UWB RF transmitter in 90nm CMOS

A 6–9GHz RF transmitter fabricated in a standard digital 90nm CMOS technology and targeted for WiMedia UWB bandgroup 3 and 6 is presented. The transmitter features high linearity, low spurious emission, low power and small chip area. Measured data show — 5.7dBm output power, −1.41dBm OIP3, −47dBc LO leakage and −33.8dBc sideband rejection with only 72mW from a 1.2V power supply at a minimal chip area of 0.24mm
