Hi,
I have designed a circuit as shown in the last link.
However, i'm getting a very small bandwidth at Vout of about 6MHz (ac analysis). or maybe it isn't small?
the waveform of Vout (transient analysis) looks fishy as its offset is about 300mV. Is there anything wrong with the circuit itself?
The compensating capacitor was being calculated and doing some trial and error.
I would like to have a stable circuit with the highest bandwidth it can afford for some analyses.
Please advise. thanks!
