A transmitter is provided. the transmitter includes a hybrid feedback circuit and a hybrid driving circuit. The hybrid feedback circuit compares a reference voltage with a feedback voltage in closed-loop, determines whether to perform polarity reversal according to a mode control signal, controls power output according to a comparison result and the mode control signal, and generates a first output signal. The hybrid driving circuit, coupled to the hybrid feedback circuit, receives the first output signal of the hybrid feedback circuit, generates a transmitter output signal according to an input data, and generates a second output signal according to the transmitter output signal. The first output signal and the second output signal are transmitted back to the hybrid feedback circuit.

A fingerprint detection apparatus, a mobile device using the same and a manufacturing method thereof are provided. The fingerprint detection apparatus comprises an image sensing integrated circuit and a spatial filter disposed on the image sensing integrated circuit. The spatial filter has adjacent light tunnels for restricting an incident angle of light to the image sensing integrated circuit to prevent scattered light from entering the image sensing integrated circuit.
