Abstract
PURPOSE:To enhance the dielectric strength of a switch circuit, by providing a switching element between the output of thes witch circuit, which is connected between a power source and the earth, and a load. CONSTITUTION:When a signal is not applied to a terminal T1, an MOSFET Q1 is turned off, and the voltage between the source and the gate of an MOSFET Q2 is zero approximately, and therefore, the FET Q2 is turned off. However, the junction between the source and the drain of the FET Q2 is forward bias, and a capacitor Cc is charged up to a power source voltage VDD. When a signal is applied to the terminal T1, FETs Q1 and Q2 are turned on, and the potential at a point C jumps up to a maximum 2VDD by storage energy of resonance circuit C0 and L0, but only the voltage VDD at most is applied between drains and sources of FETs Q1 and Q2, thus preventing the breakdown of FETs.
