1. A touch sensing reading device, comprising:
an operation circuit, comprising a feedback capacitor, receiving a sensing signal through a first input terminal, receiving a driving signal through a second input terminal, feedbacking an output signal via an output terminal through the feedback capacitor and the first input terminal, wherein the feedback capacitor is coupled to the first input terminal; and
an adjustment circuit, comprising an adjustment resistor, coupled to a first input terminal of the operation circuit, providing an adjustment signal to the first input terminal of the operation circuit, adjusting the output signal through the adjustment resistor,
wherein the adjustment signal comprises a first sub-signal and a second sub-signal,
wherein the first sub-signal in the adjustment signal is set based on an inverted signal of the driving signal,
wherein the second sub-signal in the adjustment signal is set based on an inverted signal of the sensing signal.
