IR-UWB-CMOS Integrated Circuits and Antenna Arrays for Breast Cancer Detection

Speaker: Takamaro Kikkawa
Affiliation: Hiroshima University

Abstract:

Impulse radio ultra-wide-band complementary metal oxide semiconductor (IR-UWB-CMOS) integrated circuits for breast cancer detection are presented. The circuits consist of Gaussian monocycle pulse (GMP) generator and transmitter, single port eight throw (SP8T) switching matrix circuits, and 100 GS/s equivalent time sampling circuits with analog-to-digital converter. The GMP having the pulse width of 160 ps and the center frequency of 6 GHz is transmitted from a Tx antenna and the scattered signals are received by a Rx antenna. Confocal imaging is performed using a breast phantom whose characteristics are the same as those of measured breast tumors, glandular and adipose tissues.
