To minimize output offset voltage and increase circuit
accuracy, the resistor values need to meet the
conditions:
EQUATION 4-3:
4.7.2
In analog circuit design, the PCB parasitic capacitance
can compromise the circuit behavior;
a typical scenario. If the input of an amplifier sees
parasitic capacitance of several picofarad (C
which includes the common mode capacitance of 6 pF,
typical), and large R
of the circuit will include a zero. This parasitic zero
introduces gain-peaking and can cause circuit
instability.
FIGURE 4-9:
Capacitance at the Input.
One solution is to use smaller resistor values to push
the zero to a higher frequency. Another solution is to
compensate by introducing a pole at the point at which
the zero occurs. This can be done by adding C
parallel with the feedback resistor (R
selected so that the ratio C
