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.

Summary

3v3 comparator with 1v8 output. For possible future uses in ADCs. May also include other related test circuits like analogue mux, sample and hold circuit, etc.
