摘要：

This paper presents a dual-channel timed array transmitter for impulse radio ultra wide band wireless communication system. The transmitter can generate UWB pulses in two separate transmitter paths with tunable path delay difference of 0 similar to 250ps to achieve beamforming capability. Through injection locking with 800MHz input reference, the generated UWB pulse centers at 4GHz and covers 3 similar to 5GHz band with 10-dB side-lobe rejection. Fabricated in 0.18 mu m CMOS technology, the transmitter consumes 37mA at 10Mbps under 1.8V supply.
