Low-Offset Simple Video Buffer Circuit

  
This circuit has proved to be an effective video buffer and will easily drive a 75- 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 in VBE of Ql and Q2.

The supply lines should be well bypassed, 5 V or more.
