Abstract:
An analog-switch circuit (1) having: a resistor (R1); a resistor (R2); a CMOS analog switch (S1) in which a first end is connected to an input end (Vin) via the resistor (R1), and a second end is connected to an output end (Vout); and a CMOS analog switch (S2), in which a first end is connected to the first end of the analog switch (S1), and a second end is connected to a ground end via the resistor (R2). The CMOS analog switch (S2) is turned on or off in antiphase to the analog switch (S1).
