Note:
(1) Please use A4 size papers.
(2) The lab report should be submitted online individually.
(3) Use Proteus 8.10 for simulation before the lab session. In the Proteus
library, you should be able to find all the components used in the schematics.
The lab report must include both the simulation and measurement
results.
1. [Common-Source with Source Degeneration Amplifier]
(a) [20%] (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.)
(b) [15%] ( RL = ∞ ) For Vin = VIN + 0.01sin(2π102
∙ time) , plot
Vout = VOUT + υout vs time. Confirm that the amplitude of υout is
equal to 0.01 × Aυ.
(c) [15%] (RL = 50 kΩ) For Vin = VIN + 0.01sin(2π102
∙ time) , plot
Vout = VOUT + υout vs time. Does the amplitude of υout become
smaller than 0.01 × Aυ? If so, explain the reasons. (Note: Make sure
the NMOS remains in the saturation region.)

2. [Source Follower]
(a) [20%] (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.)
(b) [15%] ( RL = ∞ ) For Vin = VIN + 0.05sin(2π102
∙ time) , plot
Vout = VOUT + υout vs time. Confirm that the amplitude of υout is
equal to 0.05 × Aυ.
(c) [15%] (RL = 50 kΩ) For Vin = VIN + 0.05sin(2π102
∙ time) , plot
Vout = VOUT + υout vs time. Does the amplitude of υout still
maintain around 0.05 × Aυ? If so, explain the reasons.

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.
