Description
- [Common-Source with Source Degeneration Amplifier]
- (RL = ∞) Design and build a common-source with source degeneration amplifier, which has a voltage gain Aυ > 5 , using
NMOS (VN0104). Plot VOUT vs VIN. Is the voltage gain Aυ close to RD⁄RS? (Hint: First choose appropriate 𝑅𝐷 and 𝑅𝑆. Second, perform DC sweep to find out a 𝑉𝐼𝑁 at which the magnitude of slope is more than 5. At the same time, make sure the NMOS is in the saturation region. If not, change for another 𝑅𝐷 and 𝑅𝑆, and repeat the DC sweep again.)
- ( RL = ∞ ) For Vin = VIN + 0.01sin(2π102 ∙ time) , plot Vout = VOUT + υout vs time. Confirm that the amplitude of υout is equal to 01 × Aυ.
- (RL = 50 kΩ) For Vin = VIN + 0.01sin(2π102 ∙ time), plot Vout = VOUT + υout vs time. Does the amplitude of υout become smaller than 01 × Aυ? If so, explain the reasons. (Note: Make sure the NMOS remains in the saturation region.)
- [Source Follower]
- (RL = ∞) Design and build a source follower, which has a voltage gain Aυ > 0.5, using NMOS (VN0104). Plot VOUT vs VIN. Is the voltage gain Aυ close to unity? (Hint: First choose appropriate 𝑅𝑆 . Second, perform DC sweep to find out a 𝑉𝐼𝑁 at which the magnitude of slope is more than 0.5. Here the NMOS is always in the saturation region.)
- ( RL = ∞ ) For Vin = VIN + 0.05sin(2π102 ∙ time) , plot Vout = VOUT + υout vs time. Confirm that the amplitude of υout is equal to 05 × Aυ.
- (RL = 50 kΩ) For Vin = VIN + 0.05sin(2π102 ∙ time), plot Vout = VOUT + υout vs time. Does the amplitude of υout still maintain around 05 × Aυ? If so, explain the reasons.

Ordering Information
General Description
This enhancement-mode (normally-off) transistor utilizes a vertical DMOS structure and Supertex’s well-proven, silicongate manufacturing process. This combination produces a device with the power handling capabilities of bipolar transistors and the high input impedance and positive temperature coefficient inherent in MOS devices. Characteristic of all MOS structures, this device is free from thermal runaway and thermally-induced secondary breakdown.
Supertex’s vertical DMOS FETs are ideally suited to a wide range of switching and amplifying applications where very low threshold voltage, high breakdown voltage, high input impedance, low input capacitance, and fast switching speeds are desired.
