Abstract: This application provides an optical signal processing circuit and an electronic device, to improve a signal-to-noise ratio of an output signal of a fingerprint sensor, thereby improving a fingerprint recognition rate. The optical signal processing circuit includes a photosensitive device, an amplifier transistor T1, a switch transistor T2, a switch transistor T3, a readout circuit, a control circuit, and a voltage-adjustable power supply. When the optical signal processing circuit is in a compensation reset phase, the voltage of the gate of T1 exactly reaches a level at which the amplifier transistor T1 is turned on. Therefore, when an input voltage and a voltage increment are applied to the gate of T1, a gate-source voltage Vgs of T1 increases, and T1 amplifies an input voltage signal to generate an output signal.

Abstract: In a handwriting recognition system, a fingertip-motion sensing device has first and second body parts respectively wearable on a distal phalanx and a proximal phalanx of a finger, and a bendable bridge connecting the two body parts. An accelerometer module in the first body part generates acceleration data of the fingertip motion whereas a battery module powering the accelerometer module is in the second body part, avoiding the first body part to be loaded with the battery module so as to reduce hindrance to a user in handwriting. The bridge is wavily shaped, enabling it to be extensible and retractable to avoid spurious interference generation due to unintended movement between the first body part and the distal phalanx. The sensing device wirelessly transmits the acceleration data to a computing device, which analyzes the acceleration data to determine handwritten characters by using a machine-learning classifier, preferably a convolutional neural network.

When a response to the search signal that is transmitted by the first stylus is detected, an operating mode of the sensor controller is determined to be the first mode. When the signal transmitted by second stylus is detected, the operating mode of the sensor controller is determined to be the second mode.
