Title:
半導体スイッチ回路
Document Type and Number:
Japanese Patent JP4902323
Kind Code:
B2
Abstract:
A semiconductor switch circuit is provided that enables current consumption to be reduced even in a conduction state. A semiconductor switch circuit 100 has P-type MOS transistors Q101 and Q102 for conduction that share a source and are connected in series between an input/output terminal 101 and input/output terminal 102, a P-type MOS transistor Q103 and N-type MOS transistor Q105 having drains connected to the gate of Q101, a P-type MOS transistor Q104 and N-type MOS transistor Q106 having drains connected to the gate of Q102, and a control terminal 103 connected to the gates of the transistors. Further semiconductor switch circuit 100 is configured with the sources and back gates of Q103 and Q104 connected to the sources of Q101 and Q102. Therefore, it is possible to switch the path between input/output terminal 101 and input/output terminal 102 between a conduction state and non-conduction state by means of voltage control by voltage value Vcont of a control signal applied to control terminal 103.
