Geometric-Mean De-Embedding: A Heuristic Distributed Method for Precise Characterization of RF HEMTs

2026

Abstract

We propose a heuristic combination of conventional lumped de-embedding models [i.e., open-short (OS) and short-open (SO)] that is equivalent to a distributed model. The technique was named geometric-mean de-embedding (GM-DE), as it converges to the geometric mean of the two other methods for the single-port case. This is unlike existing distributed methods, which are often overly complicated, require additional dedicated calibration steps, and therefore have not been adopted in common practice. While lumped de-embedding has remained the mainstream method for more than three decades, our approach provides a practical yet robust pathway toward distributed deembedding. This is of utmost importance for accurate parameter extraction of RF HEMTs, particularly for the correct estimation of key performance figures like f max .

Open source

Open source is source code that is made freely available for possible modification and redistribution. Products include permission to use the source code, design documents, or content of the product. The open-source model is a decentralized software development model that encourages open collaboration. A main principle of open-source software development is peer production, with products such as source code, blueprints, and documentation freely available to the public.

Linkless embedding

In topological graph theory, a mathematical discipline, a linkless embedding of an undirected graph is an embedding of the graph into three-dimensional Euclidean space in such a way that no two cycles of the graph are linked. A flat embedding is an embedding with the property that every cycle is the boundary of a topological disk whose interior is disjoint from the graph. A linklessly embeddable graph is a graph that has a linkless or flat embedding; these graphs form a three-dimensional analogue of the planar graphs.

Logic optimization

Logic optimization is a process of finding an equivalent representation of the specified logic circuit under one or more specified constraints. This process is a part of a logic synthesis applied in digital electronics and integrated circuit design. Generally, the circuit is constrained to a minimum chip area meeting a predefined response delay. The goal of logic optimization of a given circuit is to obtain the smallest logic circuit that evaluates to the same values as the original one.
