Abstract
A temperature compensated video transmission system including a D.C.-video frequency amplifier for supplying a computer monitor wherein the operating bias for two opposite polarity type transistors are directly coupled collector-to-base, and bias to this coupling is provided through the base-emitter junctions of two serially connected transistors, the base and collectors of these transistors being directly coupled, whereby D.C. drift, with temperature, of the amplifier is prevented.
