Design And Implementation Of Liquid-Based Fine-Tunable Solenoid Mems Inductor

Peranti pasif seperti pengaruh litar bersepadu memainkan peranan penting dalam litar frekuensi radio. Walau bagaimanapun, prestasi kualiti faktor bagi pengaruh jenis ini dihadkan atas pengaruh substrat yang tinggi. Oleh itu, dalam tesis ini, bendalir boleh laras-halus pengaruh sistem mikroelektronik...
