摘要：
Inductors with both a high quality factor Q(L) and a low temperature coefficient of inductance TCL are crucial for highly stable, fully integrated frequency references. We present tapered multipath inductors in a standard CMOS technology that achieve Q(L) > 8 and TCL = 1 ppm/C-degrees in aluminum-based (Al) top metal and reach Q(L) > 19 with a TCL = 30 ppm/C-degrees in a thick copper-based (Cu) metal layer, both at 2 GHz.
