An on-chip power sensor and a millimeter-wave transmitter on a chip including the on-chip power sensor are described. The millimeter-wave transmitter can also include a coupler disposed on a transmit path, the coupler being configured to receive a transmit signal and to provide the transmit signal to an antenna. The on-chip power sensor can be configured to receive a coupled portion of the transmit signal from the coupler, and measure a transmit power of the transmit signal based on the coupled portion of the transmit signal.

Power sensor for integrated circuits

One exemplary embodiment of the present invention relates to a circuit that includes at least one RF signal path for an RF signal and at least one power sensor, which is coupled to the RF signal path and configured to generate a sensor signal representing the power of the RF signal during normal operation of the circuit. The circuit further includes a circuit node for receiving an RF test signal during calibration operation of the circuit. The circuit node is coupled to the at least one power sensor, so that the at least one power sensor receives the RF test signal additionally or alternatively to the RF signal and generates the sensor signal as representing the power of the RF test signal.

RF front-end with power sensor calibration

The present invention relates to a millimeter-wave transmitter on a chip comprising at least one transmit path coupleable to an oscillator, and an on-chip power sensor to measure at least a portion of a transmit power transmitted over the at least one transmit path. The present invention further relates to a method of calibrating a millimeter-wave transmitter on a chip and an on-chip power sensor coupleable to at least one transmit path of a millimeter-wave transmitter. The embodiments of the present invention provide a direct measure of transmit power provided within an individual one of the transmit paths of the millimeter-wave transmitter.
