Matched Resistor Networks for Precision Amplifier Applications
Design Note 502

Introduction
Some ideal op amp conп¬Ѓgurations assume that the
feedback resistors exhibit perfect matching. In practice,
resistor non-idealities can affect various circuit parameters such as common mode rejection ratio (CMRR),
harmonic distortion and stability. For instance, as
shown in Figure 1, a single-ended ampliп¬Ѓer conп¬Ѓgured
to level-shift a ground-referenced signal to a common
mode of 2.5V needs a good CMRR. Assuming 34dB
CMRR and no input signal, this 2.5V level shifter exhibits
an output offset of 50mV, which can even overwhelm
the LSB and offset errors of 12-bit ADCs and drivers.
