    Abstract: The present invention relates to a sensor circuit method for securing a sufficient Signal to Noise Ratio (SNR) by reducing the influence of noise induced from a sensor element which appears in the final output signal of a reception unit although an input signal having a relatively small amplitude is used in a sensing apparatus in which a time-periodic signal having a relatively higher frequency as compared with the speed of change of a behavior of a user or a movement of an object to be sensed, such as a capacitive sensor or an inductive sensor, is used as an input signal. Power consumption of a touch sensor chip can be reduced even without increasing the amplitude of a touch sensor panel driving signal, and a production cost for a touch sensor chip can be reduced by removing a high voltage driver.
