Numerical integration using Bezier splines

This paper describes numerical integration algorithms based upon Bezier splines. Numerical integration in the context of circuit simulation takes place in the transient analysis portion of the circuit simulators. The solution to the differential-algebraic equation system describing a dynamic circuit is obtained by formulas which formulate the solution as a Bezier function. The algorithms presented in this paper are fully investigated and developed for analog circuit simulation. SPICE program is used in testing these algorithms. Test circuit simulation results are provided to display the performance of the algorithms. >
