The intersection of the responses exhibits a combined slope
of 40 dB per decade,leading to ringing or outright oscillation.
Let’s refer to that point as the “critical intersection frequency.”
Compensation for this circuit is best accomplished with an
alternate feedback path; the response of which will dominate
at the critical intersection frequency.
A good criteria for the response of the alternate feedback
would be:
1.A response which dominates by at least an order of magnitude
(20 dB) at the critical intersection frequency.
2.The alternate feedback response should have a corner
occurring at a frequency an order of magnitude less than
the critical intersection frequency.
To provide this response,the alternate feedback components
have been selected to provide the compensating response illustrated
in Figure 6.AB in Figure 6 is the dominant feedback
path the amplifier will see in its closed loop configuration.RF
merely acts as a ground leg return impedance for the alternate
feedback loop,and should be a low value between 100 and
1000 ohms.Rd is then selected to provide the desired high
frequency gain,and Cf is selected for the alternate feedback
corner.
