Abstract

Abstract. This paper describes a new and original method
for designing oscillators based on the Normalized Determinant Function (NDF) and Return Relations (RRT)- Firstly, a review of the loop-gain method will be performed. The loop-gain method pros, cons and some examples for exploring wrong solutions provided by this method will be shown.
This method produces in some cases wrong solutions because
some necessary conditions have not been fulfilled.
The required necessary conditions to assure a right solution
will be described. The necessity of using the NDF or the
Transpose Return Relations (RRT), which are related with
the True Loop-Gain, to test the additional conditions will
be demonstrated. To conclude this paper, the steps for oscillator design and analysis, using the proposed NDF/RRj
method, will be presented. The loop-gain wrong solutions will be compared with the NDF/RRj and the accuracy of
this method to estimate the oscillation frequency and QL will be demonstrated. Some additional examples of plane reference oscillators (Z/Y/T), will be added and they will be analyzed with the new NDF/RRj proposed method, even these
oscillators cannot be analyzed using the classic loop gain
method.
