Discussion Overview
The discussion revolves around the search for a generic transistor model suitable for use in Capture CIS, particularly focusing on the ability to easily edit parameters such as K, V-Threshold, and B_f without altering channel lengths and widths. The conversation touches on the use of schematic capture tools and circuit simulation.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
- Homework-related
Main Points Raised
- One participant seeks a generic model for MOSFET/BJT transistors in Capture CIS that allows easy parameter adjustments.
- Another participant clarifies that MOSFET behaviors are influenced by width (W) and length (L), while BJT behaviors depend on fundamental parameters like those from the Ebers-Moll or Gummel-Poon models.
- A participant suggests that default SPICE models may suffice for general use, referencing older discrete parts as a benchmark for performance.
- One participant acknowledges the dependency of transistor behaviors on W and L but mentions that educational contexts often simplify this to parameters like K, threshold voltage, and early voltage for intuitive analysis.
- A later reply offers a specific model from the BREAKOUT library, indicating that it allows for the editing of the parameters the original poster is interested in.
Areas of Agreement / Disagreement
Participants express varying levels of agreement on the importance of W and L in determining transistor behaviors. There is no consensus on a single generic model for Capture CIS, and the discussion includes multiple perspectives on the adequacy of existing models.
Contextual Notes
The discussion highlights limitations in the availability of generic models and the potential need for customization in simulation tools. There is also an acknowledgment of the differences in transistor characterization in educational settings versus practical applications.
