Devices and methods related to embedded sensors for dynamic error vector magnitude corrections

Abstract

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.

What is claimed is: 
     
         1 . A power amplifier (PA) comprising:
 a PA die;   an amplification stage implemented on the PA die, the amplification stage including an array of amplification transistors configured to receive and amplify a radio-frequency (RF) signal;   a sensor implemented on the PA die, the sensor positioned relative to the array of amplification transistors to allow sensing of an operating condition representative of at least some of the amplification transistors; and   a dynamic error vector magnitude (DEVM) compensation circuit in communication with the amplifying transistors and the sensor and configured to provide a dynamic error vector magnitude compensation effect.
