Large Signal Frequency Domain Device Analysis Via the Harmonic Balance Technique
Harmonic and intermodulation distortion effects play a key role in the design and subsequent performance of analog RF/µWave systems. Due to the wide range of frequency components present in such systems, ordinary transient analysis is both extremely time-consuming and insufficiently accurate. In this paper, we present a harmonic balance version of the PISCES semiconductor device simulator. This two-dimensional device simulation tool allows for efficient, physically-based analysis of intermodulation distortion in two-dimensional device structures. Robust nonlinear relaxation methods have been developed to overcome the enormous memory and speed problems associated with fullycoupled, large-signal 2D frequency-domain analyses.
