Abstract: A noise compensating touch panel includes a touch module and a signal compensating module. The touch module includes transmission electrodes and sensing electrodes. The signal compensating module has a first input, a second input and an output. The signal compensating module couples to the touch module. The transmission electrodes receive scanning voltage signals sequentially. When the scanning voltage signals sense the touching by object at crossover points of a first transmission electrode and the sensing electrodes, the sensing electrodes provide sensing signals. The sensing signals include the value of a first parasitical capacitor. The second transmission electrode senses the value of a second parasitical capacitor which the second transmission electrode isn't touched by object when the second transmission electrode receives the scanning voltage signals. Then the second transmission electrode provides compensating signals. Signal compensating module receives the sensing signals and the compensating signals separately.

Abstract: A current-to-voltage converter which is used to receive an input current and to generate an output voltage accordingly comprises a current tracking bias circuit, a current-to-voltage unit, and a voltage clamp bias circuit. The current tracking bias circuit generates a first bias according to the input current. The current-to-voltage unit receives the first bias and the input current, and generates the output voltage according to the input current, wherein the first bias determines a range of the input current, the current-to-voltage unit has a first current control device, and the first current control device changes a current conduction level thereof in response to the first bias, such that a rising or falling speed of the output voltage is enhanced. The voltage clamp bias circuit clamps voltage levels of two ends where the voltage clamp bias circuit is connected to the current-to-voltage unit.
