The measured results for quality factor improvement and self-resonance frequency (fsr) improvement of the planar inductors implemented in 0.35-mum two-poly-four-metal (2P4M) CMOS process are presented in this paper. These inductors are fabricated on a low resistivity Si-substrate with a resistance about 33 Omega-cm. It is observed that the quality factors of planar inductors can be increased by the shunt metals from metal1 (M1) to metal4 (M4) to reduce the series resistance at low frequencies… CONTINUE READING
