Evaluate the bandwidth noise error due to offset voltage/Mechanical Engineering
The overall objective of this lab is to design a variable-gain amplifier, where the gain is controlled by a digital output of the microcontroller. The gain settings are 10, 20, 50, and 100. As preparation, design two separate circuits using different approaches. Evaluate the bandwidth, noise, error due to offset voltage, and cost. Build and experimentally measure bandwidth, noise, and offset error.
