IPC: H03K17/08
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To provide an electronic switching circuit capable of supplying input power to capacitive loads without generating excessive current and oscillation. SOLUTION: A current detection resistance 4 and a FET 2 are serially connected between an input power source 1 and capacitive loads 12 and 14.
