Next up in this series on modulated signals is an example of multi-dimensional EM design challenges: RF power amplifiers (PAs). Digital pre-distortion (DPD) is a favorite technique for linearizing PA performance. Static effects are easy to model and correct, but PAs are notorious for interrelated dynamic effects spoiling … Read More

Shift left gets a modulated signal makeover
Everyone saw Shift Left, the EDA blockbuster. Digital logic design, with perfect 1s and 0s simulated through perfect switches, shifted into a higher gear. But the dark arts – RF systems, power supplies, and high-speed digital – didn’t shift smoothly. What do these practitioners need in EDA to see more benefits from shift left? … Read More
