Capacitive-load isolation techniques in timing detector of CSRe internal target

Capacitive-load isolation technique was proposed to improve the stability and capacitive load ability of the timing detection system in internal target of CSRe. This technique can solve the overshoot and ringing problems of the circuit, without affecting its gain and bandwidth. By constructing the circuit model, the cause of the instability of the circuit is analyzed mathematically, and the rationality of the capacitive-load isolation techniques is proved in the experiment. It is demonstrated that the capacitive-load isolation technique can effectively eliminate the gain hump and the deteriorative frequency response caused by the capacitive load. (authors)
