Collections of BASIC subroutines are developed to perform
non-general circuit analyses. These subroutines are used to evaluate
the manufacturability of a functionally trimmed thick film hybrid
circuit. Nodal, sensitivity, and tolerance analyses are used to
evaluate the effectiveness of the functional trim algorithm, and an
optimization procedure to alter the nominal circuit parameter values
for adequate margins.
The computer programs are not user-interactive, and the user has
to write a separate program to incorporate the various subroutines.
The pro6rams are written for use on the HP9835A desktop computer. The
component element types discussed are limited to resistors,
capacitors, and voltage controlled current sources.
Nodal analysis is performed by LU factorization techniques, and
sensitivity analysis by the adjoint network approach. Circuit
frequency response optimization is presented usiag the Fletcher Powell
minimization procedure and quadratic polynomial fitting. A Monte
Carlo tolerance analysis routine is developed.
