DEVICES AND METHODS RELATED TO EMBEDDED SENSORS FOR DYNAMIC ERROR VECTOR MAGNITUDE CORRECTIONS

摘要

Devices and methods related to embedded sensors for dynamic error vector magnitude corrections. In some embodiments, a power amplifier (PA) can include a PA die and an amplification stage implemented on the PA die. The amplification stage can include an array of amplification transistors, with the array being configured to receive and amplify a radio-frequency (RF) signal. The PA can further include a sensor implemented on the PA die. The sensor can be positioned relative to the array of amplification transistors to allow sensing of an operating condition representative of at least some of the amplification transistors. The sensor can be substantially isolated from the RF signal.
