On the other hand, a LNPA, which this paper focuses on designing, is used to obtain a large output signal and low noise figure which can be used in harmonic feedback oscillator
as shown in Fig.
A 40mV input voltage is applied to the The charge pump (CP) circuit it generate from the multi feedback oscillator
. The charge pump has a 5 stage of inverter, each stage inverter having the energy stored capacitor.

Leeson's 1966 paper, " A Simple Model of Feedback Oscillator
Noise Spectrum," Proceedings of the IEEE, includes an equation with loaded Q multiplied by frequency offset in the denominator of an expression for noise power.
The classic feedback oscillator
lends itself to meeting these requirements, (1) while an MMIC-based implementation results in a low cost solution incorporating ancillary circuits such as buffer amplifiers, a prescaler and a frequency doubler.

In 1966, Leeson published a formula for the single-sideband (SSB) phase noise of a feedback oscillator
that is still widely used.

This paper describes an experimental 3.67 GHz surface mount, permanent magnet biased, YIG-tuned, feedback oscillator
. The oscillator's dimensions are 0.385" x 0.510" x 0.155" and weighs 3 grams.
The series feedback oscillator
, shown in Figure 3, was designed with conventional linear techniques employing S-parameters.
