Abstract :
The design of a remotely UHF powered UWB transmitter is presented in 0.13μm CMOS standard process. Power harvesting unit is based on a Dickson voltage multiplier and UWB pulse generator uses filtered combined edge method. Multi-Vt technique and CMOS logic allows pulse generator power consumption between two consecutive pulses to be reduced enough to be remotely powered. It achieves FCC compliant pulses having 1.82Vpp and a PRF of 15kHz at 10m thanks to the power harvesting unit.
