  • System and method for non-linear dimming of a light source
    Patent number: 8823287
    Abstract: In one embodiment, a light dimming module is disclosed. The light dimming module has a dimming engine coupled to a digital input interface and an output interface. The dimming engine is configured to provide a N-segment piecewise linear exponential digital control signal, and the output interface is configured to control the intensity of a light source.

  • Pulse modulation devices and methods
    Patent number: 8232902
    Abstract: An embodiment method of generating an output pulse stream comprises first pulse modulating a first multi-bit input term to generate a first one-bit pulse stream, using a bitwise logic AND to combine the first one-bit pulse stream and a second multi-bit term, thereby generating a multi-bit AND output, and second pulse modulating the multi-bit AND output to generate a one-bit output pulse stream representing a product of the first and second multi-bit input terms.
