Abstract :
The correlation between the impedance pattern for automatic noise-parameter determination and the accuracy of extracted parameters is investigated using a statistical approach. Selection criteria for near-optimal patterns are given, and a new method is proposed for automatic generation of these patterns. Simulations prove this method outperforms others using random or cross-shaped patterns
