Abstract :
We present the design and fabrication of a monolithic predistortion linearization circuit with application to externally modulated analog fiber optic links. Results indicate 24 dB suppression of 3rd order distortion at 1.3 GHz. We also present experimental results on the first fully-digital bias compensation loop. The circuit exhibits 25 dB suppression of 2nd order distortion
