## Mixed signal tests
Collection of analog and mixed signal test circuits.

Basic goal: a comparator based on the circuit in "CMOS Design" (Jacob Baker).

Extra goals:

- 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
