Abstract

PURPOSE:To obtain a switch circuit which can be applied to signals of a shorter repeated period, by connecting a capacitor in parallel to a resistance connected to the gate in the circuit where MOSFETs are connected longwise. CONSTITUTION:In the circuit where enhancement type MOSFET 1 and 1' are connected longwise between power source 3 and load 2, capacitors 7 and 8 are respectively connected in parallel to resistances 5 and 6 which drive MOSFET 1' with signals of load end 2. As a result, the charge time for the capacity between the gate and the source of FET 1' is shortened because synthetic impedances of resistance 5 and capacitor 7 as well as resistance 6 and capacitor 8 of the charge resistance are lowered. That is, the charge time for the capacity between the gate and the source of FET 1' becomes shorter for a high repeated frequency in comparison with only the parallel resistance of resistances 5 and 6, and this circuit can be applied to signals of a high repeated frequency.
