- Homework Statement
- 2. Use Cadence to simulate figure 13.38 in the book and the frequency is 10Hz. You need to plot (1) I1 and I2 in the same plot. (2) V0

Hint: 1. The voltage is amplitude, not AC magnitude

2. Ideal transformer is xfmr in Cadence

3. Use transient analysis

(See body for circuit)

- Relevant Equations
- Equations for ideal transformers.

V2 = nV1

I2 = (I1/n)

n = (N2/N1)

Here is the circuit...

Here is my work so far in cadence (I haven't put in values for other components in because the moment I saw the dot convention I started trying to figure that out).

-There apparently isn't a way in Cadence Virtuoso (the program my class uses) to change the dot convention of the ideal transformer (xfmr in analoglib).

- Another student on the class discord said they "

- I went another route and decided to have a "negative" number of turns on my secondary coil to represent the alternate direction of the windings. The equations above work out to the right sign convention if I do this. (or at least I think).

I can't just run the simulation and pick the "

At first I thought The other students method was completely wrong, but now that I look at it I think both methods might work. Though there's might be the best to go with because I don't know if the program will like that negative sign.

Any help would be appreciated.

__Where I'm at__-There apparently isn't a way in Cadence Virtuoso (the program my class uses) to change the dot convention of the ideal transformer (xfmr in analoglib).

- Another student on the class discord said they "

*just flipped the right side of the circuit*". I'm assuming they mean they flipped how that side is connected to the transformer.- I went another route and decided to have a "negative" number of turns on my secondary coil to represent the alternate direction of the windings. The equations above work out to the right sign convention if I do this. (or at least I think).

I can't just run the simulation and pick the "

*best looking*" result because I'm not familiar enough with transformers to know what I'm looking for.At first I thought The other students method was completely wrong, but now that I look at it I think both methods might work. Though there's might be the best to go with because I don't know if the program will like that negative sign.
