摘要： An average current controller configured for connection to display-components through a power switch. The average current controller includes first, second, and third comparators, an integrator, and a reference current generator. The first comparator compares a peak current level of reference current with a load current level of load current and outputs a first comparison result. The load current denotes current flowing through the display-components. The second comparator compares the peak current level of reference current with an average current level of the load current and outputs a second comparison result. The integrator integrates the second comparison result. The third comparator compares the integral value of the integrator with a predetermined value and outputs a third comparison result. The reference current generator sets the peak current level based on the first comparison result and the third comparison result and generates the reference current with the set peak current level.

摘要： Disclosed is a method and apparatus for composing a received symbol signal modulated with a bit reflected Gray code into bit information. According to an embodiment of the present invention, a positive integer of the received symbol signal having bits is assigned according to the Gray mapping rule, and a sign is determined. A value that is indicative of an arrangement of the bits constituting the received symbol signal is calculated. A boundary value in at least one bit group consisting of the bits constituting the received symbol signal is acquired, and a difference from an absolute value of the received symbol signal is calculated. The received symbol signal is converted into information per bit using a value of the received symbol signal based on the positive integer and the determined sign, the value that is indicative of the bit arrangement, and the difference from the absolute value. Therefore, it is possible to reduce complexity in bitwise decomposition for an iterative decoder inevitably used in a receiver.
