摘要： Apparatus (50) for processing a differential input signal. The apparatus (50) comprises a minimum peak detector (51) with a differential input (28). The peak detector (51) provides a first voltage being proportional to an average voltage peak at the peak detector's differential input (28). A compressor (53) is provided for processing the first voltage in order to provide a second voltage. The compressor (53) is followed by a voltage controllable current source providing a trim current that is adjustable by the second voltage. A hysteresis equipped circuit (67.1) whose hysteresis characteristics are adjustable by the trim current is part of the apparatus (50).

摘要： Apparatus (40) comprising a plurality of output buffers (41.1-41.N) for driving the columns of an LCD panel (46). A bias generator (42) is employed for providing a common biasing current (Ibias) to all output buffers (41.1-41.N). Means (43) provide information regarding the physical position of a dot to be driven on the LCD panel (46) by counting the number of incoming load signals (LD). A switchable current source (42) changes the level of the biasing current (Ibias) according to the physical position.

摘要： The invention concerns a circuit arrangement (2) for driving a display arrangement (1). Further it concerns a display arrangement (1) and a method for driving a display arrangement (1). To provide an arrangement (2) having a good offset cancellation combined with high quality illustrating of an image the circuit arrangement includes column driving means (5) for driving n column electrodes (C) and row driving means (4) for driving m row electrodes (R) of the display arrangement (1), wherein the column driving means (5) comprises n output channels (O), each output channel (O) having a column electrode (C) assigned and is arranged for providing a respective column voltage to the assigned column electrode (C), an additional output channel (OR) is arranged for providing a respective column voltage, whereas each of the n column electrodes (C) is connectable to the additional output channel (OR). The additional output channel (OR) will be calibrated at first. Then the additional output channel will successively replace the output channel (O1-On) whereas during replacement the output channels (O1-On) will be calibrated sequentially. So the time required for offset cancellation will not reduce the time for settling the column voltage.
