LOW_OFFSET_SIMPLE_VIDEO_BUFFER
This circuit has proved to be an effective video buffer and will easily drive a 75-Ω load to 1.5-V p-p output. BW is better than 20 MHz and there is less than 0.05-V dc offset, which is the difference inVBE of Q1 and Q2. The supply lines should be well bypassed, ± 5V or more.
