+## Mixed signal tests
+Collection of analog and mixed signal test circuits.
-## Please fill in your project documentation in this README.md file
+Basic goal: a comparator based on the circuit in "CMOS Design" (Jacob Baker).
+Extra goals:
-:warning: | Use this sample project for analog user projects.
-:---: | :---
+- A small array (eg 1x8) of Flash cells for characterisation
+- An alternative comparator layout using only self-biased amplifiers (no bias voltage required)
+- The digital section of delta-sigma ADC
+- Demo charge pump
+- Sample-and-hold circuit
