Description
cmIPCS is a compact model of Four-Terminal, Inline, Indirectly Heated Phase Change RF Switches (IPCSs). The model accurately predicts the thermal and electrical dynamics of the device by considering the changes in heater resistance, contact resistance, and parasitic capacitance. The thermal dynamics are modeled using a thermal-equivalent RC model, based on the physical dimensions and thermal properties of the device. The temperature feeds a behavioral model that determines if a phase transition occurs. The parasitic OFF capacitance is obtained from RF measurements. The model is validated using FEM simulations and experimental electrical thermometry of GeTe IPCS devices with different physical dimensions.
The complete model is implemented in Verilog-A, thus it enables rapid device optimization, and the design and simulation of large-scale circuits and systems composed of IPCS with varying substrates, dielectrics and PCM materials. The threshold voltages and the temperature of the heater are predicted within 92% accuracy by this model.
