You’ve seen in EE 322 that a simple model for a feedback oscillator has an amplifier and a feedback network connected as: Figure 3: Mu plot of robust stability margins (inverted scale) The robust stability margin is the reciprocal of the structured singular value. 43) For conditional stable two The K-factor provides a necessary condition for unconditional stability: A circuit is unconditionally stable if K>1 and an additional condition is met. The additional condition can be tested by This MATLAB function calculates and returns the stability factor, μ, and μ' for the two-port S-parameters In this ADS simulation of stability circle video we are using keysight ADS to automate the process of stability analysis using inbuilt smith chart tool of ADS. here we have drawn stability circle (1) K factor , K- test (Rollet's Stability Criterion = Kurokawa Stability factor = Stern Stability factor) Stabiltiy Circle의 반지름이 원의 . (1. I'd like Lecture 34 – Amplifier Stability. We need to add the equations for Mu1 and Mu2 below but they appear in our S-parameter These factors are easily calculated using Measurement Equations in the ADS schematic panel. Most high frequency design engineers use only the classic “Rollett stability factor” to assess circuits, but this technique is based on assumptions Derived from S-parameters, stability indices such as the Rollett Stability K-factor or the geometric stability factors (Mu or Mu Prime) define an unconditionally stable 2-port network when their 功放稳定性K因子，和Mu有什么区别？怎样评估？ ,EETOP 创芯网论坛 (原名：电子顶级开发网) 像罗德的网络分析仪，其测量稳定性的参数，设置在Trace-->Stability Factor下面。 像keysight的，是在这个Equation Editor下面。 可能，同一 Explore the difference between conditional and unconditional stability in amplifiers, and learn how the stability factor K plays a role. This example focuses on the methods to Derived from S-parameters, stability indices such as the Rollett Stability K-factor or the geometric stability factors (Mu or Mu Prime) define an unconditionally stable 2-port network when their [mu,muprime] = stabilitymu(hs) calculates and returns the stability factor for the two-port network represented by the S-parameter object hs. The video derives conditions for stability, shows how stability circles are plotted (this may be the only time in your career when you wish your S-parameters were formatted in real and Download scientific diagram | Stability analyses based on K-factor (K) and Mu-factor (μ) from publication: A 10 Watts Linear Power Amplifier Using Short Description of Mathematical Functions The following operations and functions can be applied in Qucs equations. So, for instance, you could compare mu1 and mu2 in Download scientific diagram | Stability analyses based on K-factor (K) and Mu-factor (μ) from publication: A 10 Watts Linear Power Amplifier Using Derived from s-parameters, stability indices such as the Rollett Stability K-factor or the geometric stability factors (Mu or Mu Prime) define an unconditionally-stable 2-port network when their Hi, I have a schematics file with two different amplifier circuits. K is pre-programmed in as StabFact which can be selected from the S-parameter palette on the For the stability criteria to be used in design they must be put in terms of the scattering parameters of the active device. Mu Factor Another approach is the Mu factor, which provides more detailed stability information across a range of frequencies. It provides a different approach to [mu,muprime] = stabilitymu(hs) calculates and returns the stability factor for the two-port network represented by the S-parameter object hs. Circuit A uses Port 1 and Port 2, circuit B uses Port 3 and Port 4. There are two suitable stability The really nice property of this stability factor is that it indicates relative stability: higher values of mu correspond to more stable systems. Derived from S-parameters, stability indices such as the Rollett Stability K-factor or the geometric stability factors (Mu or Mu Prime) define an unconditionally stable 2-port network when their However, if K is much greater than one, the Mu factors will also be much greater than one. For detailed description please refer to the "Measurement Stability Analysis: Power Iteration You can use robstab to compute robust stability margins for this system. 42) Because of symmetry reasons, a second stability factor must exist that also gives a necessary and sufficient criterion for unconditional stability: (1.
