Absfruct-A novel behavioral model generatton method focused
to symbollc analysls of analog Integrated circuits is
presenbd. The proposed method Is earried out by modeling
each MOS Transls@r (MOST) by. thelr small-signal nnUorbased
model. It Is shown that by uslag thk type of modeling,
the signal path (SP) between the output-Input nodes can be
approached. In thls way, MOST that are no1 included in the SP
lould be ellmlnated, sllowfng to see the separatlon o€ the bias
MOST and .those that are not It. Most important Is behavloral
model generation ol each MOST which provides a reduced set
of network equations and it Is rep-nted by an admittance
mat& where the order is given by the number of nudes of
the SP. Thererare,. small-slgnal characteristks ol analog clrcults
can be easily approached. The proposod method is illustrated
by compullng the hlly-symbolic *ander Function (TF) .or
the Operatlonal hnsconductance AmplLCier (OTA) Mlller and
compared wlth HSPICE slmulalion.
