The methodology described in this article for creating a PWL noise source is an effective way of generating general fα noise for time-domain circuit simulations. The benefit of using digitally-interpolated noise waveforms is significant. Using an external computer program to produce digitally-interpolated PWL noise sources removes the burden of spectrally shaping the noise from the circuit simulator, eliminating the need for high-order analog filters. By designing a custom FIR interpolating filter, unique types of spectral shaping are possible without increasing the computational burden
