Hi to all,
I want a circuit of Current source with 3-dB level BW of 400MHz and higher.
I tried to simulate (SPICE) a simple combination of actual single OpAmps and P-Ch MOSFETS, & R, C components
and could get maximum 235MHz of OpAmp LMH6629 & MOSFET at 100mA output level.
Can some one advise a transitor (or both components, or a new schematic) that can give desired BW?
Please include your current schematic and we can take a look.
the circuit is:
Limitation: single polarity supply 3.0V (2.9V)
