<P>PROBLEM TO BE SOLVED: To provide a semiconductor device and a sample-hold circuit using a MOS transistor switch having a low on-resistance in an on-state and a low off-leak current in an off-state. <P>SOLUTION: When a PMOS transistor M11 is in an on-state, a PMOS transistor M12 becomes in an on-state to connect a back gate terminal of the PMOS transistor M11 with a source terminal of the PMOS transistor M11. When the PMOS transistor M11 is in an off-state, a PMOS transistor M13 becomes in an on-state to connect the back gate terminal of the PMOS transistor M11 with a power supply voltage terminal VDD1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
