Question 1 of 27070

What special type of diode is capable of both amplification and oscillation?

🔍 Key Concepts

• Semiconductor diode characteristics such as forward and reverse bias behavior • The difference between ordinary rectifier diodes and special-purpose diodes (Zener, tunnel, point-contact) • How negative resistance regions in a device’s characteristic curve can lead to amplification and oscillation

💭 Think About

• Which type of diode has a region in its voltage–current curve where current decreases as voltage increases, creating negative resistance? • Among the options, which diode is specifically known for use in high‑frequency oscillators and amplifiers, instead of simple rectification or voltage regulation? • Think about where you’ve seen each device used: which one is common in voltage regulators, which one in very early detectors, and which one in microwave or high‑frequency circuits?

✅ Before You Answer

• Match each choice with its primary typical application (e.g., voltage regulation, simple detection, high‑frequency oscillation/amplification). • Recall which device’s I‑V curve has a peak and valley region that provides negative resistance. • Eliminate any options that are mainly used for rectification or voltage regulation rather than active amplification/oscillation.
