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

Refer to README for the sample project documentation.
