1. An apparatus, comprising:
a current supply coupled to a light source; and a controller coupled to the current supply including:
a comparator comprising a first input, a second input and an output,a stochastic state machine, coupled to the first input of the comparator, to generate a plurality of stochastic values, anda signal density register, coupled to the second input of the comparator, to hold a signal density value,wherein the output of the comparator is based on a stochastic value of the plurality of stochastic values and the signal density value, wherein the controller is configured to provide a stochastic control signal to the current supply, the stochastic control signal to control a light intensity output of the light source. |
