A CMOS UWB transmitter for possible use for medical and biological imaging based on radio-wave induced ultrasound

Medical and biological imaging based on radio-wave induced ultrasound with a single source capable of irradiating multiple signals of different frequencies simultaneously can be implemented using ultra-wideband (UWB) technique. Development of a low-cost miniature UWB CMOS transmitter that can be used for this medical application is presented. The UWB transmitter designed using a 0.25-μm CMOS process can generate and transmit both monocycle pulses from 140 to 350 ps and impulses from 100 to 300 ps which contain many concurrent frequencies such as 3.1-10.6 GHz of the UWB spectrum.
