Abstract
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.
Claims21
A millimeter-wave transmitter on a chip comprising
- at least one transmit path coupleable to an oscillator;
- an on-chip power sensor to measure at least a portion or a transmit power transmitted over the at least transmit path.
A method of calibrating a millimeter-wave transmitter on a chip, the method comprising:
- providing transmit power within at least one transmit path;
- directing at least a portion of the provided transmit power to a power sensor on the chip;
- measuring the portion of the provided transmit power at the power sensor on the chip.
An on-chip power sensor coupleable to at least one transmit path of a millimeter-wave transmitter, the on-chip power sensor comprising:
- a resistor formed in a layer of the chip, wherein a resistance of the resistor is temperature dependent.
