# Industrial Specification: Amplifier Stage

## 1. Technical Definition
Electronic circuit stage that increases the amplitude of electrical signals within a signal generator.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-10 V input, 1-100 V output, -40°C to 85°C ambient**. Failure boundary: **Input voltage &gt; 12 V causes saturation, output current &gt; 500 mA causes thermal runaway, junction temperature &gt; 150°C**, Mechanism: **Semiconductor junction breakdown at 12 V reverse bias, thermal runaway due to positive temperature coefficient above 150°C junction temperature**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.
