Abstract :
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˜250 ps to achieve beamforming capability. Through injection locking with 800 MHz input reference, the generated UWB pulse centers at 4 GHz and covers 3˜5 GHz band with 10-dB side-lobe rejection. Fabricated in 0.18 μm CMOS technology, the transmitter consumes 37 mA at 10 Mbps under 1.8 V supply.
