ABSTRACT:
A voltage follower circuit includes a differential amplifier which has first and second transistors. The output of the collector of the second transistor is fed to the base of the second transistor as a feedback input through a third transistor and a diode. The diode operates as a direct current level-shift circuit. A video signal is fed to the base of the first transistor, and the output of the voltage follower circuit is taken from the base of the second transistor.
