  8. Developed a Project Plan

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
