Abstract

The invention provides a novel CMOS (Complementary Metal Oxide Semiconductor) infrared transceiver. The CMOS infrared transceiver includes an IR transmitter circuit, an IR receiver circuit, and an IRdiode configured to transmit or receive IR signals. CMOS elements, such as PMOS current mirrors, PMOS switches, NMOS switches, NMOS current mirrors, and receiver enabled PMOSFET switches, are used inCMOS infrared transceivers. The CMOS infrared transceiver can have the advantages of increased integration level, less occupied space and lower cost.

Description

technical field [0001] The present application relates to an infrared transceiver, in particular to a single-tube infrared transceiver. Background technique [0002] Infrared (IR) transceivers are widely used in IR communications, such as remote controls for home electronic equipment such as televisions, air conditioners, and VCD equipment. Traditionally, IR transceivers take up a lot of space and cost. Therefore, a new type of IR transceiver that takes up less space and costs less is urgently needed. Contents of the invention [0003] According to one embodiment, a CMOS single-transistor infrared transceiver may include an IR transmitter circuit, an IR diode, and an IR receiver circuit. Standalone declarations will be added here later. [0004] The application provides a CMOS infrared transceiver (100) comprising: [0005] Infrared transmitter circuit (100A), the infrared transmitter circuit includes: [0006] a PMOS current mirror having a first PMOSFET and a second...
