Abstract-Design, simulation, and implementation of low profile microstrip spiral inductors for high power Industrial, Scientific and Medical (ISM) applications at the high frequency (HF-3-30 MHz) range are given for the first time. An accurate analytical model and algorithm have been developed to determine the simplified lumped element equivalent model parameters for spiral inductor and its physical dimensions. Five different spiral inductors are then simulated with a planar electromagnetic simulator using the physical dimensions obtained for the desired inductance values with the analytical method. The implementation method and substrate selection for spiral inductors at the HF range are given in detail for high power applications. The spiral inductors are then constructed on 100 mil Alumina substrate and measured with network analyzer. It is found that analytical, simulation and measurement results are in close agreement and the analytical method and algorithm that have been developed can be used to accurately determine the physical dimensions, and the resonant frequency of the spiral inductor for the desired inductance value.

Scalable modeling methodology of on-chip spiral interleaved transformer is proposed. The novel equivalent circuit based on ladder topology is composed of lumped elements and their parameters are completely derived from the physical structure. The circuit topology enables to express the inductive and capacitive coupling effect between half turn segmented wires accurately. The circuit also contributes to obtain the scalability related to wire width/space, length, and diameter. In this model, coupling capacitance between adjacent wires is given by considering parallel paths through oxide layer and Si substrate. The model simulation result matched the measurement result of a fabricated transformer TEG with the error less than 5% for wide frequency range upto quasi-millimeter wave band.

“…The most used on-chip inductors are spiral inductors for their low cost and ease of process [2]. As the operation frequency increases, various physical mechanisms such as skin effect, proximity effect and electric-magnetic penetration into substrate make spiral inductors difficulty to be well modeled and designed [3].…”

“…The general methodology of inductor synthesis is such a loop that gets the design parameters by making use of the simulator and then optimizes the process parameters and layout geometrical parameters to get the most satisfactory results by various optimization ways. According to the kinds of simulator, the way of synthesis can also be classified into three kinds: synthesis based on Numerical Simulation [5], synthesis based on empirical models [3] [7] [8] and synthesis based on Neural Network [1]. Among the three ways, the methodology based on empirical models is mostly used because there is a lot of mature research results focused on empirical models, not only analytical expressions but also equivalent circuits.…”

We develop a novel synthesis way to effectively generate CMOS spiral inductor's layout parameters using artificial neural network and genetic algorithm. An accurate neural network model for CMOS spiral inductors is firstly developed based on measured results from TSMC 0.13um MM/RF process with the frequency range of 1-20 GHz. The neural network model is further integrated in the synthesis simulator kits called SPUNK. An innovative synthesis technique is then applied in which genetic algorithm based optimization is adopted. Our methodology promises to provide greater accuracy than previous results in the frequency range while able to minimize the time cost for spiral inductor design.
