A computer approach to transistor circuit design


"The design of amplifiers is usually approached through experimental study. This thesis proposes a mathematical approach, using a digital computer to predict the performance of an active transistor circuit (a frequency equalizer circuit to compensate for the RIAA¹ recording frequency characteristics) prior to the actual construction of the physical system. The simple but powerful computer analysis method will be based upon the nodal equations of the complete circuit. The primary aim is to design a circuit which would give a desired frequency-gain characteristic. The complete set of simultaneous complex nodal equations describing the circuit operation is then written. Based on these equations, the IBM 1620 digital computer is programmed to pick up the transistor "y" parameters and solve the complex elements of the matrix at each frequency. The gain, phase shift, input and output impedances are then determined. The theoretical results are compared with results obtained in the laboratory"--Abstract, page ii.
