Design an infrared wireless optical mouse system and a dual-band infrared receiver

Abstract

This paper describes an Infrared wireless optical mouse system and a dual-band Infrared receiver. The presented system is designed with dual-band Infrared receiver. The proposed dual-band Infrared receiver is designed to receive two kinds of signals that are modulated by two different carrier frequencies. One is 37.9kHz carrier frequency for conventional remote controls and the other is 113.7kHz carrier frequency for enhanced data rate communications. The proposed dual-band Infrared receiver chip was fabricated in a 0.5um CMOS process. The presented system employs 113.7kHz carrier frequency to enhance the data-rate and to make immune against ambient Infrared noise for the optical communication and it was designed to FPGA device. The presented system is tested in a standard PC system as a HID compliant mouse and it transfers data at average rate of 2.7kb/s via optical link.
