Choosing Resistor V alues
Unity-Gain Configuration
The MAX4108 is internally compensated for unity gain.
When configured for unity gain, the device requires a
small resistor (typically 24
) in series with the feedback
path. This resistor provides better AC response by
reducing the Q of the tank circuit formed by parasitic
feedback inductance and capacitance.
Inverting and Noninverting Configurations
The values of the gain-setting feedback and input resis-
tors are important design considerations. Large resistor
values will increase voltage noise, and will interact with
the amplifier’s input and PC board capacitance to gen-
erate undesirable poles and zeros, which can decrease
bandwidth or cause oscillations. For example, a nonin-
verting gain of +2, using 1k
resistors combined with
2pF of input capacitance and 0.5pF of board capaci-
tance, will cause a feedback pole at 128MHz. If this
pole is within the anticipated amplifier bandwidth, it will
jeopardize stability. Reducing these 1k
resistors to
100
will extend the pole frequency to 1.28GHz, but
could limit output swing by adding 200
in parallel with
the amplifier’s load. Clearly, the selection of resistor val-
ues must be tailored to the specific application.
