What this 214 project looks like:
In case you’re wondering, this is the ‘topology’ of the amplifier we’re building. Click on the image for a more readable view.
But this is just for looks. When it comes to entering this into our simulator, you have to define it all by hand. An example would be:
* Input NMOS Gain devices M1a cn vim tail 0 nch214 W=’W1′ L=’L1′ M1b cp vip tail 0 nch214 W=’W1′ L=’L1′ * First Stage NMOS Cascodes M2a out1p vbc_n cn 0 nch214 W=’W2′ L=’L2′ M=1 M2b out1m vbc_n cp 0 nch214 W=’W2′ L=’L2′ M=1And so on. Once you can start to visualize a circuit network though, its faster just entering it in by hand rather than drawing it.
