How do you calculate resistance in SPICE circuit?
If MNAME is specified, then the resistance may be calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model.
What kind of resistor is the Spice resistor?
The SPICE Resistor block represents a SPICE-compatible resistor. You can specify the resistance in one of the following ways: As process information that the block uses to calculate a resistance value
What are the four equations of SPICE circuit?
SPICE allows circuits to contain linear dependent sources characterized by any of the four equations i = g v v = e v i = f i
How to generate a Simulink model of a resistor?
The temperature at which to simulate the resistor. This parameter is visible only when you select Fixed temperature for the Model temperature dependence using parameter. The temperature at which the resistor parameters were measured. Generate C and C++ code using Simulink® Coder™. Run the command by entering it in the MATLAB Command Window.
How does a voltage controlled resistor work in spice?
Voltage-Controlled Resistor. To sense current, SPICE uses a voltage source VSENSE (0V). It’s set to 0V so there’s no effect on the output voltage. The other source, ERES, generates the voltage across the “resistor” based on the sensed current times your desired resistance VALUE={I(VSENSE)*10K}.
How to construct a SPICE model for a component?
The SPICE model for a component probably draws upon the content of the datasheet for it… So, how does one construct a SPICE model when the data-sheet is available for reference? I’m looking at LTSpice
How do you make a voltage controlled resistor?
A simple addition to the above resistor model gives you a voltage-controlled resistor. All you need is a controlling voltage to multiply the resistor value: V = I x R x Vc. Here’s a subcircuit for this device.
