Abstract
A CMOS IR transceiver includes an IR transmitter circuit, an IR receiver circuit, and an IR diode configured to either emit or receive an IR signal. CMOS elements, such as a PMOS current mirror, a PMOS switch, a NMOS switch, a NMOS current mirror, and a receiver enabling PMOSFET switch are used in the CMOS IR transceiver. The CMOS IR transceiver may have advantages of increased integration, occupying less space, and lower cost.
