Non-linear Characteristic compensating circuit null for TV transmitter

摘要

PURPOSE: To provide the compact and chipped non-linear compensation circuit for TV transmitter of low power consumption with simple circuitry. ;CONSTITUTION: The device consists of an amplifier and black amplitude compensation circuits Z11-Z1N at the N stage. The amplifier is constructed emitter grounded by a transistor TR11 and a resistor R14. In the circuits Z11-Z1N, the anode terminals of dildes D111-D11N are parallely connected and the parallel connection terminal is parallely connected with the amplifier resistance TR14. By adjusting the resistance values of the variable resistances VR111-VR11N, the level of turning on and off the diodes D111-D11N and the resistance value of the resistors R151-R15N, the adjustment of the amplifier degree of the amplifier is enabled.;COPYRIGHT: (C)1995,JPO
