| 摘 要： | This paper presents a transmitter IC with BPSK modulation for an ultra-wide band system.It is based on up-conversion with a high linearity passive mixer.Unlike the traditional BPSK modulation scheme,the local oscillator (LO) is modulated by the baseband data instead of the pulse.The chip is designed and fabricated by standard 0.18μm CMOS technology.The transmitter achieves a high data rate up to 400 Mbps.The amplitude of the pulse can be adjusted by the amplitude of the LO and the bias current of the dri...
