✦ Synopsis

A parametric amplifier circuit is described. The nonlinearity involved is an abrupt one and a method of analysis of "relaxation oscillations" is preferred to techniques assuming quasi-linearity. This leads to a physical understanding of the cycle of oscillations as well as quantitative relationships which are helpful to the designer. The stability problem is also solved establishing the switching requirements. * A current saturable inductance is so named to signify that the nonlinearity in the magnetic characteristic is such that in the region of saturation a large change in magnetic flux is associated with a small change in the magnetic field. The name was first suggested to the author in 1953 by Prof. R. Rudenburg of Harvard University.
