The system consists of two circuits. The first converts the composite video signal to a differential signal using amplifiers IC 1 and IC 2. Using a differential signal reduces line loss and distortion ...

While researching “Zero Drift Amplifiers” as a follow-up to my video on Instrumentation Amplifiers I noticed the little schematic the front page of the LTC1049 datasheet which is shown here.

Although the modern op amp has excellent power-supply rejection in the audio range, this drops off rapidly at video and RF frequencies. ... In high-speed op-amp circuits, ...

Back in the '60s, there was an intriguing circuit article titled "Starved-Circuit Amplifier" published in Popular Electronics magazine. It used a sharp cut-off pentode with a 3-MΩ load resistor ...
