Abstract

CMOS equivalent-time sampling circuits for impulse-radio ultra-wideband (IR-UWB) breast cancer detection system was developed. The minimum phase resolution of 9.77 ps and the sampling rate of 102.4 GS/s were achieved for Gaussian monocycle pulses (GMP) with the pulse width of 210 ps. The input analog GMP was converted to digital data by use of a 4-bit analog-to-digital circuit. Target phantom images were reconstructed by confocal imaging algorithm.
