improvements in current steering from the supply voltages.
This model type is typically used to model high-speed
amplifiers; however, it has come in useful when modelling
function circuits that require special considerations.
SECTION C:
MULTIPLE-POLE/ZERO
MACROMODELS
The multiple pole/zero (“M”) macromodel allows modeling
of more than two poles and any additional zeros in the op
amp macromodel. All of the macromodels using this topol-
ogy are in the MPZ_MOD subdirectory on the disk. The
input stage of this model is similar to the standard and
enhanced op amp macromodels; however, after the input
stage that similarity disappears. By using various circuit
topologies the gain stages, pole stages, zero stages and pole/
zero stages are constructed. The number of each of these
stage types is dependent on the performance characteristics
of the amplifier being modelled. An effort is made to match
the macromodel performance as closely as possible to the
tested gain/phase of the op amp. The output stage also offers
