Spectrum Software has released Micro-Cap 11, the eleventh generation of our
SPICE circuit simulator.
For users of previous Micro-Cap versions, check out the
new features available in the latest version. For those of you who are
new to Micro-Cap, take our
features tour to see what Micro-Cap has to offer.
Micro-Cap includes a built-in filter design program which directly creates filter schematics.
The active filter designer supports low pass, high pass, bandpass,
notch, and delay filters that can be set up with a Butterworth,
Chebyshev, Bessel, elliptic, or Inverse-Chebyshev response. Circuit implementations include
Sallen-Key, MFB, Tow-Thomas, Fleischer-Tow, KHN, Acker-Mossberg, and Tow-Thomas 2. The passive
filter designer supports low pass, high pass, bandpass, and notch
filters than can be set up with a Butterworth, Chebyshev, or elliptic
response. The two implementations for passive filters are standard
The created filter can be sent to a new circuit, to a currently
loaded circuit, or can be made into a macro component that is
easily accessed through the Component panel or menu. The designer also
offers a choice of opamps to use for an active filter and produces filters
with exact passive values. These can then be optionally mapped with the Fit To Standard Value
command into the best series / parallel combinations of standard passive values.
The filter designer lets you quickly view Bode, Step, and
Impulse responses for the filter that is being designed.
