Abstract : A circuit analysis is given for a parametric amplifier operating under conditions of linear supergeneration with a pumping frequency generator which has a square envelope. The substitutional circuit and simplifying assumptions used in the analysis are given. Formulas are derived for voltage gain, frequency response, passband width and phase shift for the cases of direct amplification and frequency conversion. A low-frequency model of a superregenerative parametric amplifier is built and tested to varify the circuit analysis. The results are tabulated and graphed. A comparison of the theoretical and experimental data shows satisfactory agreement. Possible sources of error are discussed.
