I've already run on an RC circuit and on an inverter, but all the analog
circuits I find (for example, model files) are too complex.

What's the simplest circuit with CMOS transtors for a newbie who wants to
run a simulation that they can mentally understand?

(a picture of the topology would be great)

It took a while, guessing at the xtor & resistor values, but I've at
least started a DC Analysis on that.

Thanks!

1. Current mirror
2. Cascode
3. Differential pair
4. Common-mode feedback

Learn those, and you're an analog designer.
They're all very simple.

For example, a current mirror is merely two transistors of the same size
with the same bias voltage such that the drain currents are the same.

My advice:
Understand the 4 circuits above; simulate them; understand them; and
you'll be a bona-fide analog circuit designer.

For example, the texts will say the purpose of the cascode is to increase
the output impedance of the current mirror ... but they confuse things
just so they can write 1000-page CMOS Design textbooks!

Likewise, as a dozen so-called analog designers what the purpose of an op-
amp is, and they'll likely say it's something along the order of high
gain, but that too is only making something simple complex.

KISS is what analog design is all about.

BTW, the Cadence software is nothing but the opposite of KISS. There is
analog EDA software out there that is extremely simple - just google and
you'll find it.
