Abstract : A time-shared program, SPEEDY, is discussed. The program is for small signal analysis of high frequency active circuits. It is based directly upon 2-port interconnections through the scattering matrix, thus eliminating continuous conversions of parameters of previous routines. Program advantages are speed of calculation, due to the generality of S parameters and the limitation to 2-ports; the convenience of accepting measured S parameter data, and the consequent avoidance of transistor equivalent circuits. The program includes two unique subroutines: one that handles all four possible combinations of parallel and series 2-port interconnections, and one that converts 2-port common emitter transistor parameters to common base or common collector configurations.
