Project Summary

Design a continuous-time, memoryless, time-invariant circuit, generating an output voltage from the provided input voltage, while maximizing the magnitude of the output voltage. The format of the output waveform is irrelevant, though a sinusoidal output is recommended. Any MOSFET models may be used. A SPICE simulation displaying the desired specifications as well as a physical implementation of the circuit design are created. The output should look similar to the picture shown below.

As shown, the output is a function of the input with (4V1) being the final voltage, 1 [V]. This means that:

  1. The maximum gain must be met at approximately 1/8 of a volt.
  2. The gain must be matched at 5/8 of a volt
  3. The gain must be matched with opposite polarity at 3/8 and 7/8 of a volt.
  4. The output voltage must be 0 [V] at (V1), (2V1), (3V1), and (4V1). These voltages should be assumed to be 1/4, 1/2, 3/4, and 1 [V] respectively.

Continuous-Time: A varying system whose domain, time, is a continuum. The function's domain is an uncountable set.

Memoryless: The system output must at any time be dependent on only the input.

Time-Invariant: A time-invariant system has a time-dependent system function that is not a direct function of time. The time-dependent system function is a function of the time-dependent input function.

Use Cases

  1. Physical testing of circuits for IO specifications
  2. Simulation of circuits

Project Goals and Key Deliverables

Expected end result of the project, what the customer can expect to receive at the end of the project.
