Abstract: A first circuit includes a first chain of identical stages defining first and second delay lines. A second circuit includes a second chain of identical stages defining third and fourth delay lines. The stages of the second chain are identical to the stages of the first chain. A third circuit selectively couples one of the third delay line, the fourth delay line, or a first input of the third circuit to an input of the first circuit.

Abstract: An X-ray detector includes a first circuit with an NPN-type bipolar transistor and a second circuit configured to compare a voltage at a terminal of the NPN-type bipolar transistor with a reference value substantially equal to a value of the terminal voltage which would occur when the first circuit has been exposed to a threshold quantity of X-rays.
