Abstract :
A fully custom designed CMOS transceiver chip for high frequency ultrasound imaging applications is described. The chip consists of nine transceiver channels with a programmable beamformer. On the chip, 8 bit 250 MS/s A/D converters digitize analog signals from the transducers and nine 3 Kbyte/channel SRAM store the digitized data for each of the nine channels. The chip was fabricated in a 0.35 mum standard CMOS process. The area is 26.83 mm2 and its total power consumption is below 1.5 W at 3.3 V power supply
