Abstract

This paper presents a 3-5 GHz, high output amplitude, carrier-less based Ultra Wideband (UWB) transmitter for wirelessly powered RFID application. The UWB transmitter consists of a baseband pulse generator, a driver amplifier and an output on-chip filter. The baseband pulse generator and the driver amplifier are designed as zero DC power consuming circuit, which enables scalable power with the pulse rate. IC pad and bonding wire parasitics are considered to be absorbed as part of output filtering network, realizing package co-design. The simulation result shows that the proposed transmitter radiates 2.34 pJ/pulse energy with 1.63 V pulse amplitude. The total energy consumption under 1.8 V power supply is 18 pJ/pulse, corresponding to 13% energy efficiency.
