Abstract: A pen analog front end includes an analog signal processing unit connected with an input sensor. The analog signal processing unit processes an analog input signal that the input sensor receives from an input device. An analog-to-digital converter converts the analog input signal into a first digital input signal. A digital signal processing unit synchronizes the first digital input signal and reference sync data preset to the input sensor and processes a position signal and a data signal of the input device.
