added key testbenches, schematics etc.
This is a mixed-mode project featuring a 8-bit SAR-ADC, with offset calibration. The logic section is synthesized using the openlane digital flow.
The adc is composed of a top-plate sampled CDAC, with a capacitor array of mimimum sized MIM caps.
The comparator is a single-stage regenerative comparator, with a MOM array for trimming ADC offset.
The simulation is carried out using ngspice using the mixed-mode xspice capabilities. The digital section is synthesized using yosys that can then be bridged to/from the analog section.
The layout is created using magic as a pcell generator and drc checker, while the connection of the design is done using klayout.
