Egidio Ragonese & Giuseppe Palmisano of STMicroelectronics & University of Catania present a 3-stage transformer-loaded cascode 24-GHz LNA for Automotive Radar. The transformers use a multi-layer interleaved spiral inductor structure. Momentum EM simulation and optimization of inductance and Q-factor are compared to measurements with Cascade Microtech prober, Vector Network Analyzer (VNA) & Noise Figure Analyser. Layout [...]
