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.

Claim (Index 15):
A method for operating a device that communicates via inductive coupling, the method comprising:\n generating, by a transmitter (Tx) unit of the device, a transmit signal, the Tx unit including a radio frequency Tx; receiving, by a Tx control unit of the device, an indication of a target Tx output, the Tx control unit including circuitry that stores a look-up table having a plurality of calibration data sets, determining a first calibration data set associated with the target Tx output from the look-up table and based on the indication of the target Tx output, wherein the plurality of calibration data sets is generated during testing at a device level, and each of the plurality of calibration data sets is associated with a different target Tx output and a plurality of settings of a component of the Tx unit associated with the different target Tx output, and outputting at least one control signal based on the first calibration data set to control at least one setting of the component of the Tx unit of the plurality of settings of the component, wherein the at least one setting is configured to tune the Tx unit to generate the target Tx output.
