This paper presents the design methodology for an on-chip inductor in 180 nm CMOS technology, intended for a fully integrated LC oscillator. The design method uses the model based on the physical interpretation of the inductor, and optimizes the design with respect to the Q-factor. Resulting from the optimization procedure, the inductor is designed for the on-chip LC …

On-chip inductors and transformers play a crucial role in radio frequency integrated circuits (RFICs). For gigahertz circuitry, these components are usually realized using bond-wires or planar on-chip spirals. Although bond wires exhibit higher quality factors (Q) than on-chip spirals, their use is constrained by the limited range of realizable ...
