A scalable model combining the advantages of the compact model and space‐mapping neural network (SMNN) has been presented to characterize radio‐frequency behaviors of on‐chip spiral inductors. The physics‐based T equivalent circuit model has been used for constructing the proposed scalable SMNN model. All values of the T model elements are fast and accurately extracted based on the mathematical formulations...
Accurate measurement data are a prerequisite for the equivalent circuit modeling of on‐chip devices. In this paper, the open and transmission line de‐embedding methods for on‐chip spiral inductors have been compared and analyzed by electromagnetic simulation with 130‐nm 1P6M BiCMOS process. Compared with the open de‐embedding technique, the characteristic impedances and propagation constants of left...
Poles and zeros of the transfer function determine the performance and the key features of the circuit network, such as phase, gain, and bandwidth. In this paper, the contribution of the poles and zeros to the transfer function has been shown. The factors ηp and ηz are proposed to account for the poles contribution to the peak and the zeros contribution to the valley of transfer function, respectively...
