Components
• Primitive components (resistor, capacitor, diode, inductor, mutual inductor)
• MOSFET, JFET, Bipolar transistors
• Relay
The four-terminal relay is a voltage controlled relay tied between terminals t1 and t2.
The voltage between terminals ps and ns controls the relay resistance. The relay
resistance varies nonlinearly between ropen and rclosed, the open relay resistance and
closed relay resistance, respectively. These resistance values correspond to control
voltages of vt1 and vt2 respectively.
• Ideal switch
Single-pole multiple-throw switch with infinite off resistance and zero on resistance.
The switch is provided to enable you to reconfigure your circuit between analyses.
When the switch is set to position 0, it is open. In other words, no terminal is connected
to any other. When the switch is set to position 1, terminal 1 is connected to terminal 0,
and all others are unconnected. When the position is set to position 2, terminal 2 is
connected to terminal 0, and so on.
The switch can change its position based on which analysis type is being performed
using the xxx_position parameters.
• Transformer
• Delay Line
The delay line model is a four-terminal device with zero output impedance and infinite
input impedance. The output between nodes p and n is the input voltage between nodes
ps and ns, delayed by the time delay td and scaled by gain.
