This interpretation is based on the Kurokawa's first harmonic approximation or descriptive function [14].
This oscillation condition can be extended, by means of the descriptive function, to the Kurokawa's first harmonic approximation [14].
Even if the first harmonic approximation is an attractive method, it is important to remember that the first harmonic approximation is an approximation and more accurate when the signal of the oscillator is a purer tone.
m] compression for first harmonic approximation is more valid for FET than for BJT.
osc]) = 0 the cross frequency is the first harmonic approximation oscillation frequency.
L] proper analysis have been defined, it can be extended to the first harmonic approximation.
osc]) < 0, is a first harmonic approximation of the descriptive function as defined by Kurokawa [15], and this will be shown in the next paragraphs.
osc]) < 0 shall be complemented with the equations in Table 2 for the first harmonic approximation (this is not sufficient condition to guarantee the start-up).
The crossing point is the oscillation frequency as first harmonic approximation, which is better for FET devices than for BJT devices.
osc] will cross over zero, then it will be the oscillation frequency as first harmonic approximation.
In this situation, the cross frequency is the oscillation frequency as Kurokawa defines the first harmonic approximation.
Its first harmonic approximation response behaves as a negative impedance generator.
