Negative Impedance Converter

 

[spacer]

Netlist Form

An instance of a negative impedance converter (NIC) has the following Nexxim netlist syntax:

Axxx n1 n2 n3 n4 [TYPE=V|I] [K1=val] [K2=val] COMPONENT=negative_impedance_converter

n1, n2, n3, and n4 are the nodes connected to the converter. The entry COMPONENT=negative_impedance_converter identifies the element.

Description

Units

Default

TYPE

V = Voltage, I = Current

None

V

K1

Voltage transfer ratio

None

1

K2

Current transfer ratio

None

1

Netlist Example

AnicI 1 2 0 0 Type=I K1=1.5 K2=1
+ COMPONENT=negative_impedance_converter

 

Notes

1. Absolute values are used for computations. A positive value is used even if K1 and K2 are negative.

2. Values of exactly zero are not allowed for either K1 or K2. If a zero value is supplied or is implied through omission, a value of 1.0e-9 is assigned.

3. For option V:

V1=-|K1|*V2

I1=-|K2|*I2

4. For option I:

V1=|K1|*V2

I1=|K2|*I2
