Abstract
The present invention relates to a position detector and a touch sensing device of using same with SNR enhancement. In one embodiment, the position detector has (P+1) inputs, each input for receiving an input signal associated with a position, P being a positive integer, and P operational amplifiers, each operational amplifier having a non-inverting input and an inverting input, where the inverting input of the j-th operational amplifier is electrically connected to the non-inverting input of the (j+1)-th operational amplifier, and the non-inverting input and the inverting input of the j-th operational amplifier are electrically connected to the j-th input port and the (j+1)-th input port, respectively, j=1, 2, 3, . . . , (P−1).
