Small‑Signal MOSFETs
Small‑Signal MOSFETs

Operating Principle: A semiconductor device whose output current is voltage‑controlled. For small‑signal analysis, its amplifier delivers linear signal amplification when operating in the saturation region.

Key Features: High input resistance, low noise, favorable temperature stability and strong radiation resistance.

Typical Applications: Suitable for low‑power‑consumption scenarios including portable equipment and signal switches.
