Model resistor for circuit envelope analysis
The Resistor block models a resistor within the SimRF™ circuit envelope simulation environment. For an introduction to RF simulation, see the example, Simulate High Frequency Components.
The block implements the relation
R represents the resistance, as a function of temperature.
i(t) represents the current through the capacitor at time t.
v(t) represents the voltage across the terminals of the capacitor at time t.
SimRF current and voltage signals consist of in-phase (Ik) and quadrature (Qk) components at each frequency fk specified in the Configuration block:
Specify the resistance, R0,
as a real number greater than zero. Specify the units of the resistance
from the corresponding drop-down menu. The default value of this parameter
To simulate thermal noise in a resistor, select this check box. Then, in the Configuration block dialog box, also select the Simulate noise check box. By default, both Simulate noise check boxes are selected.
This parameter inserts a current noise source with the single-sided
power density of 4
k is the Boltzmann constant
T is the value of the Temperature parameter, in degrees Kelvin. (Also located in the Configuration block.)
