# Examples The following repositories contain example circuit designs, each having a `cace/` subdirectory with a specification input (the datasheet), and a set of testbench schematics which are used by CACE to measure all specified parameters, generate results, and analyze them to determine circuit performance over corners. Example circuit repositories: | Design | Description | PDK | |----------------------------|----------------------------|-----| | [ota-5t](https://github.com/mole99/ota-5t/) | A simple 5-transistor OTA | Sky130A | | [sky130_ef_ip__opamp](https://github.com/RTimothyEdwards/sky130_ef_ip__opamp) | Operational Amplifier | Sky130A | | ... | ... | ```{note} Send us a PR if you want to add your design! ```
