Abstract: An amplifier of a transmitter includes an input that receives an input signal and generates an amplified signal at an output. A digital power meter is coupled to the input of the amplifier, generates an estimated amplified signal, and determines peak and average powers of the estimated amplified signal. An output power detector coupled to the output of the amplifier determines peak and average powers of the amplified signal. A controller coupled to the digital power meter and the output power detector determines an estimated crest factor based on the peak and average powers of the estimated amplified signal, an amplified crest factor based on the peak and average powers of the amplified signal, and an error vector magnitude based on the estimated and amplified crest factors. The controller, which is also coupled to the amplifier, then adjusts operation of the amplifier based on the error vector magnitude.

Abstract: To reduce image artifacts induced by temperature variations associated with display pixels of an electronic display, processing circuitry may process temperature sensing data to obtain an average temperature and a temperature distribution of the electronic display.
