How to Start a Career in AMS (Analog Mixed-Signal) Design

The semiconductor industry is one of the fastest-growing and most technologically advanced fields in the world today. Among its many specialized domains, Analog Mixed-Signal (AMS) design stands out as a crucial area that bridges the gap between the analog and digital worlds. With the rise of IoT devices, automotive electronics, sensors, and communication systems, the demand for skilled AMS engineers has grown rapidly. In this blog, we’ll explore how to start a career in AMS (Analog Mixed-Signal) design, including the skills you need, educational pathways, industry tools, and career growth opportunities.

Introduction to AMS Design

Before diving into how to start a career in AMS (Analog Mixed-Signal) design, it’s essential to understand what AMS design is all about. AMS circuits are those that combine both analog and digital components within a single chip.

  • Analog circuits process continuous signals—like sound, voltage, or current—such as amplifiers, filters, and oscillators.
  • Digital circuits process discrete signals—like binary data (0s and 1s)—such as microcontrollers, memory, and processors.

An Analog Mixed-Signal (AMS) system integrates both these domains, enabling real-world signals (analog) to interact with digital logic. Common AMS components include Analog-to-Digital Converters (ADCs), Digital-to-Analog Converters (DACs), Phase-Locked Loops (PLLs), and power management ICs.Understanding this integration is key when learning how to start a career in AMS (Analog Mixed-Signal) design, since it requires knowledge in both analog and digital domains.

Educational Background

The first step in how to start a career in AMS (Analog Mixed-Signal) design is acquiring the right educational background. Most AMS engineers come from Electrical, Electronics, or Communication Engineering disciplines.

A. Bachelor’s Degree

A Bachelor’s degree in Electronics or Electrical Engineering is typically the foundation. Courses such as:

  • Electronic Devices and Circuits
  • Analog and Digital Electronics
