SERAFIN

Single-Ended Operational Amplifier Characterization loosely based on AC²E.

Dependencies:

• pynut
• pyspectre

Installation

With pip:

$ pip install git+https://github.com/augustunderground/serafin.git

From source:

$ git clone https://github.com/augustunderground/serafin.git
$ pushd serafin
$ pip install .

Example

A few things need to be adjusted to run the example:

• Correct PDK path in ./example/gpdk180.yml
• Derived statements for transistors in ./example/sym.scs
• Change nmos and pmos name in ./example/sym.scs according to PDK

import serafin as sf

pdk = './example/gpdk180.yml'
net = './example/sym.scs'
ckt = './example/sym.yml'

sym = sf.operational_amplifier(pdk, ckt, net)

rsz = sf.random_sizing(sym)
prf = sf.evaluate(sym, rsz)
