Abstract
A system may include control logic and a PWM generator configured to generate a PWM (Pulse Width Modulated) signal. The PWM generator is configured to generate the duty cycle of the PWM signal dependent on a duty cycle value generated by the control logic. The control logic stores an inverse focal point value and is configured to generate the duty cycle value by processing the inverse focal point value and a temperature value indicating a current temperature according to the equation of a parabola.
