摘要： An output stage of an integrated class-A amplifier in a technology adapted to a first voltage and intended to be powered by a second voltage greater than the first one, including: one or several transistors of a first channel type between a first terminal of application of the second voltage and an output terminal of the stage; transistors of a second channel type between this output terminal and a second terminal of application of the second voltage, wherein: a first transistor of the second channel type has its gate directly connected to an input terminal of the stage; at least a second and a third transistors of the second channel type are in series between the output terminal and said first transistor, the gate of the second transistor being connected to the midpoint of a resistive dividing bridge between said output terminal and the gate of the third transistor, and the gate of the third transistor being biased to a fixed voltage.

摘要： A method for detecting the warm-up of a television CRT includes the following steps during a warm-up phase of the tube: providing the CRT with warm-up signals during predetermined line periods at the initial portion of frames; and detecting the cathode current of the tube during the occurrence of windows in correspondence with the predetermined line periods in order to enable black level regulation loops. The windows have a width smaller than a line period and are approximately centered on the line periods.
