Seminar on Understanding Electronic Component Characteristics with LTspice

The Institute for Engineer Education at Nihon IR is set to host a seminar focusing on how to utilize LTspice to understand the intrinsic characteristics of electronic components such as inductors, capacitors, MOSFETs, and CMOS ICs. This open seminar aims to blend theoretical knowledge with practical simulation, making the learning process relatable to real-world applications.

In the fields of circuit design, layout planning, and evaluation, understanding the characteristics of components is crucial. It transcends mere empirical knowledge; participants will learn the necessity of quantifiable comprehension based on equations and repeatable verification through simulation. However, diving into SPICE (Simulation Program with Integrated Circuit Emphasis) can often present challenges, including managing different model types, library integration, and various measurement and calculation commands. The seminar is structured to tackle these common hurdles by educating participants on the fundamental characteristics of electronic components while simultaneously mastering the practical use of LTspice.

Seminar Overview

• - Title: Understanding the Fundamental Characteristics of Electronic Components with LTspice and Mastering SPICE
• - Date and Time: June 4, 2026, from 10:00 AM to 5:00 PM
• - Format: Held at the Nihon IR headquarters seminar room, with an option for online participation via Zoom
• - Capacity: 7 attendees for on-site participation (No limit for online participation)
• - Fee: 49,500 yen (tax included)
• - Instructor: Masashi Aoki, Representative of TEQ Consulting

Course Details

This course features LTspice, which is a free SPICE simulator distributed by Analog Devices. Participants will learn about the essential characteristics of electronic components and key points regarding SPICE utilization in a systematic manner. To deepen the understanding required for practical work such as design and evaluation, the characteristics of inductors, capacitors, and MOSFETs will be explained using equations, coupled with simulations including transient analysis, AC analysis, and FFT analysis to validate results.

Furthermore, by addressing an essential aspect of SPICE analysis—model management—this course will provide insight into the characteristics and limitations of compact models, behavioral models, S-parameter models, and IBIS models. Participants will learn about model integration and library organization (.lib/.sym/.mod), how to utilize the .measure command for data reading and calculations, processing steps using raw files, and exporting results, all while analyzing actual outcomes.
