A change in temperature can affect the performance and characteristics of a circuit. The components most affected by a change in temperature include semiconductors, resistors, capacitors and inductors. All of these components have an inbuilt temperature dependence model parameter such that performing a temperature sweep will change component and subsequent circuit behavior.

15.1. Temperature Coefficients

For a resistor, the change in its nominal value due to a change in temperature is defined as:

(15.1)

where:

TC1 – linear temperature coefficient (ppm/°C),

TC2 – quadratic temperature coefficient ...
