Abstract :
A next-generation ultra-wideband (UWB) pulse generator with a biphase function is reported. To obtain ultrashort duration pulses, a novel speeding-up AND circuit and biphase modulator circuit were developed. The IC was fabricated in a 0.13-μm-gate InP-HEMT technology, which has a gm of 1520 mS/mm and a fT of 195 GHz. A pulse with a full width at half maximum of 9 ps and a 15-ps biphase modulated pulse were obtained. The power consumption of the ICs were 620 mW and 640 mW, respectively.
