<font size=3>I started with an Arp-style quantizer that I found at this
site.<br>

</a>I enhance it a bit with changes to the clock oscillator, parallel (vs
ripple) counter, and an improved pulse generator to sample the quantized
voltage. After prototyping it I also added some hysteresis to the
input. If I spent more time with it I would work on the hysteresis
and the interaction with the 0 reference adjustment a bit more although
it works. I wanted to be able to put in pre-quantized voltages
(e.g. from my CV keyboard) and have them quantize exactly to their
original values. The hysteresis makes this a bit complicated and I
think I ended up close enough. I also included a lag circuit which
follows the quantizer or can be used separately.<br><br>

I also use a quantizer program for the PSIM. Several have been
written. They basically follow the same architecture as suggested
with the A/D and D/A.<br><br>
