modelR
Spice-style resistor of the analog electrical library
Extends from Interfaces.SpiceTwoPort (TwoPort interface for Spice-style models).
Information
The Spice-style resistor has a reference resistance value computed at the reference temperature, Tnom, and for a relative area of Area=1. It changes its value as a function of the circuit temperature and the relative area occupied by the resistor.The heating port may remain unconnected, in which case the device is being simulated at a constant temperature of Tnom.
Parameters: R: Reference resistance (default value = 1 Ohm) Tnom: Reference temperature (default value = 300.15 oK) TR1: Linear temperature variation coefficient (default value = 0 1/oK) TR2: Quadratic temperature variation coefficient (default value = 0 1/oK2) Area: Relative area occupied by resistor (default value = 1)
