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.

System and method for non-linear dimming of a light source

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.

Pulse modulation devices and methods

An interface circuit includes an input terminal, a controlled current sink, a current measurement arrangement, and a logic circuit. The input terminal is configured to receive an input signal. The controlled current sink is operably coupled to the input terminal, and is operable to controllably take up a current from the input terminal according to a transmission signal. The current measurement arrangement is configured to generate a current measurement signal based on the current taken up by the current sink. The logic circuit is operably coupled to receive the current measurement signal and the input signal, and is configured to generate a signal depending on the input signal.
