Abstract

Many studies for improving the phase noise characteristic are based on evaluating the characteristics of designed circuit. Because the oscillator acts as a nonlinear positive feedback circuit, it is difficult to expect the oscillation frequency and the amplitude accurately. Then, we proposed the Fr oscillator circuit which satisfied the impedance matching requirement. The effective approach can be examined because it is thought that the behavior of the element in the oscillator circuit can be understood by the open circuit of this circuit. This paper describes that the characteristic of the open circuit of the Fr oscillator is corresponding to it of the closed circuit well.
