Abstract: A method for increasing a signal to noise ratio of a capacitive touch device and a capacitive touch device and a touch panel using the same are provided. The capacitive touch device includes a first sensing electrode, a second sensing electrode, a touch detector, a resonant inductor and a detection signal output circuit.An output terminal of the detection signal output circuit outputs a detection signal, such that the resonant inductor and an equivalent capacitor of the first sensing electrode are resonant, and the first sensing electrode receives a resonant sinusoidal wave. When an electric field signal detected by the detecting terminal of the touch detector is smaller than a preset value, it is determined that the capacitive touch device is touched.
