Question

Problem: Design an amplifier that can take an input of ±0.5V from a source with an internal resistance of 100 ohms and deliver it to a 100 ohm load with good linearity and less than 10% attenuation. Requirements: 1. You are limited to DC supplies of ±5V. 2. You are limited to a single transistor (CD4007 MOSFET, 2N3904 NPN BJT, or 2N3906 PNP BJT). 3. You are not allowed to use op-amps. 4. You should be able to explain the choice of circuit, transistor, how the circuit works, and design tradeoffs.

Step 1

The CD4007 MOSFET is a good choice for this application because it has a high input impedance and low output impedance, which means it can handle the input voltage range and provide good linearity. Show more…
