2 stages op amp design
You are required to design two stages op amp as shown in the figure below. GBW of the op amp is 750MHz. Find the require range of R and calculated the phase margin. All assumption should observe no peaking (set 3xGBW) in the bode plot.
PM = arc tan ( f2 / GBW ) , CL = 2pF
Anyone can provide the working solution? Thanks!
Added after 43 minutes:
the formula, GBW = gm/2piCL where the gm is refer to gm1 or gm2 ?
