Abstract
This specification discloses methods and systems for controlling a NFC (near field communication) transmitter output with enhanced accuracy. This is achieved by first doing a device and/or system level calibration of the Tx (transmitter) by testing at the device and/or system level. Then using the testing results to generate a set of Tx calibration data, which will be used by a Tx control unit to control the Tx outputs (such as Tx output power, Tx output voltage, Tx output current, etc.) with enhanced accuracy. In some embodiments, the Tx control unit controls the Tx output with enhanced accuracy by using the Tx calibration data to tune one or more of the following: (i) Tx supply, (ii) Tx driver, (iii) matching network.
