IC power amplifier for generating high voltage required to control CRT

摘要

The amplifier (1) presents an input terminal (7) which receives a low voltage (Va) generated by an amplifying stage (5). An output terminal (8) delivers the high voltage generated by the amplifier. The amplifier comprises two MOS transistors (9,10), a current source (11) and a diode (12). The first transistor is connected to the amplifier output and a second reference voltage (VDD). The diode is connected between the gate and source of the second transistor.
