Abstract:In this paper, a simple Verilog-A implementation of Lorentzian noise spectra is introduced that can be used in compact models for the frequency-domain simulation of low-frequency noise in electronic devices. For this purpose, a thermal noise source is combined with a low-pass filter as realized using laplace_nd Verilog-A function in order to achieve Lorentzian noise behavior. This modeling approach can be implemented in any Verilog-A compact model and provides the means for bias-dependent Lorentzian trap modeling. This approach is evaluated in commercial simulator. Application examples are provided to demonstrate the capabilities of this approach.
