Abstract
The circuit for measuring a bio-stimulating and bio-signal according to an embodiment of the inventive concept may include a bio-stimulating signal generating circuit, a bio-signal electrode, a switch block, first and second resistors, and a bio-signal measuring circuit. The bio-stimulating signal generating circuit may generate a bio-stimulating signal in a bio-stimulating mode. The bio-signal electrode may to deliver the bio-stimulating signal generated in the bio-stimulating mode and receive a bio-signal in a bio-signal measuring mode. The switch block may be turned on in a case where a voltage of the bio-stimulating signal is greater than a first reference voltage or lower than a second reference voltage. The first and second resistors may be serially connected between the bio-signal electrode and the switch block and divide a voltage of a signal of the bio-signal electrode according to whether the switch block is turned on. The bio-signal measuring circuit may measure voltage signals divided by the first and second resistors or measure a signal of the bio-signal electrode, according to whether the switch block is turned on. The first reference voltage may be greater than the second reference voltage.
