Abstract
A frequency modulated continuous wave (FMCW) light detection and ranging (LIDAR) system that includes an optical source to generate light at a target frequency. The system also includes a first transistor to transmit a modulation current through a modulation path that includes the optical source and a modulation resistor. The system also includes electro optical circuitry coupled to the first transistor to produce a phase locked loop. The system also includes a second transistor to transmit a bias current through a bias path that includes the optical source and is separate from the modulation path, wherein the bias path is separate from the modulation path.
