Hi, ^^
I want to design a buffer connected to the output node of preamplifier.
The output signal of preamplifier is influenced by capacitive load,
and I want to probe the output signal of preamplifier. Therefore, buffer is necessary.
1. Small input capacitance of the buffer is hoped(<100fF).
2. Load capacitance of the buffer may be 20pF(including PAD and oscilloscope).
Therefore, buffer has to have a large driving capability because the speed of
preamplifier is over 1MHz.
How do I design this buffer?
thank you, all.
