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:

  • Analogue mux for ADC
  • 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 for Flash programming voltages
  • Sample-and-hold circuit

Refer to README for the sample project documentation.
