Introduction  In the previous blog, you learned how IPn is obtained graphically based on the polynomial representing a general non-linear device. More specifically IP3 and IP2 are the most looked at parameters for many RF components. In this las...

Introduction  In the previous blog post, we learned how the various intermodulation products are generated by non-linearities with multi-tone signals.  In this blog post, we will show the method to evaluate the IPn; especially the one ...

by Maxwell Kreizinger  Introduction  This summer, as a rising junior studying electrical engineering at Cal Poly San Luis Obispo, I interned at Analog Devices with the Central Applications group in San Jose. The team wanted to investigate ...

Introduction   In the previous blog, we have seen how the polynomial representation predicts the non-linearities generating the undesired frequencies that are harmonics and different intermodulation products IMn.  Some of the...

Introduction In my previous blog, we have seen how the polynomial expression giving output y(t) versus input x(t) preserves the frequency integrity: y(t) contains the same frequencies entered at x(t) as wanted for linear devices!    &...

You took time off to raise your children and want to get back into the workforce. So, what’s next? How do you do that in these challenging times when an Applicant Tracking Software program is reading your online resume and the responses you get...

 Introduction In my previous blog, we familiarized ourselves with some terms related to linearity or non-linearity that impact circuit behaviors, especially when RF functions are involved. In this blog post, we will establish a step-by-step, th...

Introduction Non-linearity is the enemy for many functions since it deviates from the nice proportional relationship Vout = K*Vin. K is just a constant scalar term. This is what design engineers want to get for their amplifiers, transducers, sensing...

By Kuo-Chang and Marie-Eve Carre When Do We Have an Amplifier or an Oscillator? When designing an amplifier, we all have faced the risk of seeing it unstable and getting an oscillator instead. The opposite is true as well: when trying to design an o...
