Kb. Ashby et al., HIGH Q INDUCTORS FOR WIRELESS APPLICATIONS IN A COMPLEMENTARY SILICONBIPOLAR PROCESS, IEEE journal of solid-state circuits, 31(1), 1996, pp. 4-9
Rectangular spiral inductors with Q's over 12 have been built in a hig
h-speed complementary bipolar process and characterized for use in wir
eless applications. An accurate broadband model for the inductors has
been developed, and a test filter and mixer hare been built to verify
the performance of the inductors and the accuracy of the model.
