Quasi-static elastography is a widely applied ultrasound method in which RF data acquired in tissue at different states of deformation are correlated to estimate displacements and strain (displacement gradient). A recent development is the introduction of ultrafast plane-wave imaging where element data are beam-formed after collection to reconstruct the image lines. Several beam-forming strategies...
A world-band triple-mode SOC compliant with 802.11a/b/g is realized in 0.13 mum CMOS technology. This SOC features multiple integrated capless LDOs to be compatible with DC/DC supply for low current consumption and minimizing external BOMs. With supplying by a DC/DC converter, the measured 2.4 GHz/5 GHz sensitivity is -77.5 dBm/-74 dBm at 54 Mbps, and TX 2.4 GHz/5 GHz 54 Mbps EVM is -32 dB/-30 dB...
