A behavioural inductor where the inductance is programmable by the voltage on the 'inductance' net.
A 100mH inductor is shown for reference.
A behavioural inductor where the inductance is programmable by the voltage on the 'inductance' net. A 100mH inductor is shown for reference.
Changing the expression to V(A)/(I(R2.nA) would allow the capacitance to be programmed by the current in R2.
The expression can be scaled. For example:
would produce a 100mH inductor with a V(inductance) of 1V rather than 100mV.
BEWARE! A negative value of control parameter will produce a negative capacitance. Adding an ABS() function will prevent this:
