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.
When the transistor gain is compressed, by decreasing [g.sub.m] as Kurokawa defines the first harmonic approximation, [Y.sub.T] crosses over zero.
The crossing point is the oscillation frequency as first harmonic approximation, which is better for FET devices than for BJT devices.
As in the previous cases, if the transistor [g.sub.m] is compressed the frequency response of [Z.sub.T] = [Z.sub.res] + [Z.sub.osc] will cross over zero, then it will be the oscillation frequency as first harmonic approximation. This approximation is better for FET than for BJT, because FET input capacity has a minor modification with compression.
In this situation, the cross frequency is the oscillation frequency as Kurokawa defines the first harmonic approximation. In the same way as in the previous cases, this approximation is better for FET than for BJT.
