20100105155DIGITAL TRIMMING IN A MICROELECTRONIC DEVICE - Digital trimming logic is included in a microelectronic device of a type that produces an output signal in response to an input signal and a threshold signal. Trimming logic values are produced in response to a clock signal that is applied to the device in a trimming mode. The clock signal can be applied to a device pin that is used in normal operation to provide an output signal, thus allowing the pin to serve a dual function. The trimming logic changes the trimming logic value in response to the clock signal until the trimming logic value reaches a trim value at which the threshold signal is substantially equal to the input signal. The trimming logic then stores the trim value in a non-volatile memory and enters a locked mode in which further trimming is prevented and the device is ready for normal operation.04-29-2010
20100155627METHODS AND APPARATUSES FOR PERFORMING COMMON MODE PULSE COMPENSATION IN AN OPTO-ISOLATOR - In an opto-isolator, a common mode pulse compensation circuit is provided that senses when a common mode pulse event occurs and that adds current to the LED drive current to compensate for a decrease in the LED drive current caused by the occurrence of the event.

In addition, the common mode pulse compensation circuit is capable of being implemented with LEDs that operate at very low drive currents, which allows the power consumption requirements of the opto-isolator to be reduced.06-24-2010
