Discussion Overview
The discussion revolves around the use of PSpice simulation software to analyze the sensitivity of piezoresistance as a function of temperature. Participants explore the challenges of defining temperature parameters and conducting temperature sweeps in simulations, as well as the underlying concept of piezoresistance itself.
Discussion Character
- Exploratory, Technical explanation, Debate/contested, Homework-related
Main Points Raised
- One participant is attempting to define the sensitivity of piezoresistance using a specific equation but encounters issues with the "temp" variable not changing during a temperature sweep.
- Another participant suggests that the issue may be related to not defining the limits for the temperature sweep in the simulation file.
- A third participant asks for clarification on what piezoresistance is, indicating a need for conceptual understanding.
- One participant provides a brief explanation of piezoresistance and offers a method to model temperature changes using a thermistor in PSpice, including a sample subcircuit for a thermistor.
Areas of Agreement / Disagreement
Participants express varying levels of understanding regarding the use of temperature in PSpice simulations, with some seeking clarification on concepts while others provide technical suggestions. There is no consensus on the best approach to resolve the initial problem presented.
Contextual Notes
Participants mention potential limitations in defining temperature parameters and the need for specific configurations in the simulation software, but these aspects remain unresolved.
