Differential equivalent time sampling receiver for breast cancer detection

A radar-based breast cancer detection system by use of impulse-radio ultrawideband (IR-UWB) integrated circuits was developed. This paper presents a 3–10GHz UWB differential equivalent time sampling receiver for breast cancer detection, which is assembled on a printed-circuit-board by wire bonding. A sampling clock generator including phase interpolator (PI) and multiplexer (MUX) reduced a jitter noise to 0.9 ps which was integrated from 1 kHz to 10 MHz. Equivalent time sampling of 102 GSps was obtained.
