Zusammenfassung:	The present invention relates to a touch sensor noise minimization system, which can remove noise in a high-frequency band. The touch sensor noise minimization system includes: a cascaded integrator-comb (CIC) filter unit which converts a sampling rate of an input signal received from a sigma-delta ADC; a low pass filter unit which removes high-frequency noise included in a signal that has passed the CIC filter unit; a decimation unit which decimates the signal that has passed through the IIR notch filter unit; and an infinite impulse response (IIR) notch filter unit which secures a stop band from the signal that has passed through the decimation unit. 본 발명은 시그마 델타 ADC로부터 수신되는 입력 신호의 샘플링율을 변환하는 CIC(Cascaded integrator-comb) 필터부; 상기 CIC 필터부를 통과한 신호에 포함된 고주파 노이즈를 제거하는 저역 통과 필터부; 상기 IIR 노치 필터부를 통과한 신호를 데시메이션하는 데시메이션부; 및 상기 데시메이션 필터부를 통과한 신호로부터 저지 대역(stop band)을 확보하는 IIR(Infinite Impulse Response) 노치 필터부;를 포함하는, 터치 센서 잡음 최소화 시스템에 관한 것이다.
