Abstract: Systems and methods are disclosed for operating a highly linearized resistance for a switch through use of a bootstrapped features. In one exemplary implementation, there is provided a method and system that implements a method for operating a circuit configured to provide a highly linearized resistance including receiving a signal via a bootstrapped switch, coupling the received signal to a gate if the received signal is high, receiving a signal via a switch control input coupled to a high impedance element. Moreover, the method includes coupling the high impedance element to the gate and turning off the switch via a gate turn off when the gate turn off pulls the gate low.

Abstract: A circuit is disclosed for determining which of a multiplicity of LED strings in an illumination system has a fault. A group of circuits determines the maximum, minimum, midpoint between maximum and minimum, and average voltage of the group of LED string voltages in use, and examines the statistical properties of the LED string voltages. Comparators are used to find the strings which have the highest and lowest operating voltages, and to compare the midpoint and average voltages to determine whether the highest or lowest voltage string is responsible for causing a fault in the illumination system operation. Memory means are used to keep the said determined string turned off to prevent faulty operation.

Abstract: A phase shift generation circuit has an edge detector for generating first and second edge signals indicating first and second edges of an input pulse signal. The circuit comprises a divide by N circuit that divides the frequency of a first clock signal by N. The circuit comprises a pulse counter, which receives the first edge signal and the second clock signal, and outputs a group of signals representing the number of the second clock pulses between occurrences of the first edge signal. The circuit has a first recycling timer that outputs a group of pulses as a uniformly spaced group across the period of the input pulse. The circuit also has a second recycling timer that outputs a group of pulses as a uniformly spaced group across the period of the input pulse. The first and second recycling timers are used to generate a phase shifted output pulse.
