High Speed Operation
When the feedback around the op amp is resisitive (R
F
), a
pole will be created with R
F
, the source resistance and
capacitance (R
S
, C
S
), and the amplifier input capacitance
(C
IN
4pF). In low closed loop gain configurations and
with R
S
and R
F
in the kilohm range, this pole can create
excess phase shift and even oscillation on high speed
amplifiers. Because the LT1457’s phase margin is very
high, this problem is minimal. However, a small capacitor
(C
F
) in parallel with R
F
eliminates this problem. With R
S
(C
S
+ C
IN
) = R
F
C
F
, the effect of the feedback pole is completely
removed.
