Abstract: A touch sensor and a signal generation method thereof are provided. The touch sensor includes: an input signal generation unit generating an input signal; a reference signal generation unit delaying the input signal by a predetermined time to generate a first signal; a plurality of touch sensing signal generation units having a touch pad and delaying the input signal differently according to whether or not the touch pad is touched to generate a second signal; a plurality of variable delay units varying a delay time in response to a control signal and delaying the second signal in response to the varied delay time to generate a varied second signal; a plurality of touch signal generation units generating a touch signal according to a difference in delay time between the first signal and the second signal; and a control unit receiving and analyzing the plurality of touch signals, generating touch outputs when the touch pad is in a touched state, and supplying the control signals to the variable delay units when the touch pad is in a standby state. Accordingly, the delay value may be automatically adjusted even when the delay value, which has been initially set, is varied due to an external environment, so that the touch pad may be prevented from being mis-operated.

Abstract: Provided are an automatic impedance adjuster and a control method thereof. The automatic impedance adjuster includes: a pulse signal generating part for generating a pulse signal having a pulse width varied in response to a pulse width control signal; a signal processing part including a plurality of channels having a plurality of first input sensors and a pulse width correction channel having a second input sensor, not outputting the pulse signal when a touch object is in contact with the first and second input sensors, and outputting the pulse signal when the touch object is not in contact with the first and second input sensors; and a controller for outputting a non-contact state when the pulse signal is detected and outputting a contact state when the pulse signal is not detected during a normal mode, entering an automatic impedance adjustment mode to control the pulse width control signal when a pre-determined time elapses, and entering the automatic impedance adjustment mode to control the pulse width control signal when the pulse signal is not detected through all the plurality of channels or the pulse width correction channel. The automatic impedance adjuster includes a specific channel for checking an operating environment. When an operation signal of the specific channel is detected or operation signals of all the channels are detected, the automatic impedance adjustment operation is performed to prevent malfunction of the impedance adjustment operation. In addition, malfunction of a touch sensor due to variation of the operating environment can be prevented to improve operating reliability of the touch sensor.
