Title: Protective device for switching circuit
Inventor: KAWADA SHIGERU
IPC: H01L27/02
Filed: 1986-04-22
Abstract: PURPOSE:To facilitate maintaining normal operation of one end of a switch for a positive or negative input signal by providing a means which makes the impedance of the other end of the switch low when the switch is not conducting. CONSTITUTION:It is assumed that, when an FET 130 is turned OFF and disconnected state is provided between a terminal 101 and a common terminal 1, a negative excess input signal is added to the terminal 101. The source 112 of an FET 110 is biased to a negative potential and a part of the current flows through a grounding point 114 by the applied negative signal. Although the gate of the FET 110 is biased to a grounding potential through a terminal 103 and the FET 110 is essentially OFF, it is conductive by the negative signal applied to the source 112 and a current path is formed between the source 112 and the drain 113. As a terminal 102 to which the drain 113 is connected is grounded through a low impedance by an FET 120, the negative excess signal does not reach the common terminal 1. To the contrary, if a positive excess signal is applied, the FET 110 is turned into punch-through state and, also in this case, the current is introduced to the grounding terminal by the FET 120 and the OFF state of the FET 130 can be maintained.
