This is a test of the xschem
tool. The schematic file sc_bandgap.sch
contains the current top-level schematic of a switched capacitor bandgap reference.
The subcircuit transmissiongate.sch
and transmissiongate.sym
is used to show the hierarchical structure of xschem
.
An ideal one pole opamp has also been created in the opamp_onepole
schematic and symbol.
It is assumed that the xschemrc
from the open_pdks
install is handle by the user of this repo.
The repo was developed with the Skywater 130nm PDK install in the /usr/local/share/pdk
directory.
Follow the guide on open_pdks
The simulation
directory also contains a gnuplot
script, used to plot the data generated by the xyce
simulator.
This is an alternative to the waveform graph inside xschem
, which is included in the sc_bandgap.sch
schematic.
