ABSTRACT: An open-source simulator to design and implement circuits and systems, replicating the results from the Field Programmable Analog Array (FPAA) is presented here. The fundamental components like the transistors, amplifiers and floating gate devices have been modeled based on the EKV model with minimal parameters. Systems including continuous-time filters and the analog front-end of a speech processing system have been built from these basic components and the simulation results and the data from the FPAA are shown. The simulated results are in close agreement to the experimental measurements obtained from the same circuits compiled on the FPAA fabricated in a 350 nm process [read more...]
