Verifying some web Schmitt trigers

1-st i attempted to make sense of

this beast (src.) . . . is the T3 right polarity? coz i couldn't get this thing to generate any useful output that way ... anyway there's what it end up :

and it's damn slow for dif. input stage -- where the good point is it's having a high impedance input

---

2-nd we got something called CURRENT-MODE SCHMITT TRIGGER

or  PULSE_COMPLETING_SCHMITT

if it's an OE output -- then here some more realistic boundary for it :

it appears fast and even faster - but input seems to be very low impedance???

next i should try some j-Fet 1-s ...

custom 1.2V logic "ser.-s" revised

what was revised ::

(( not too very good as seen from time.now() ))

what we got ::

(( an inverter + additional schmitt 3-ger ))

(( always fun to test new oscillators ... ))

(( basic , simple ))

(( X-Tal type ))

another pointless post about custom 1.2V logic

X-perimental Schmitt Trigger

the higher power v. of ?the lower power v.

The TEST ::

 the Schmitt can go about 3.6MHz . . . the logic follows below 1MHz

(should revisit one or the other)

The uncompacted sub-circuits ::

teh XC-trigger almost but not exactly the JK-trigger

The 3ger ::

confirming hysteresis

practical 'ow 'er logic test

needed a 1:10 duty oscillator - so i revised/-studied/-tested some trivial generator types . . . the schmitt-inverter showed up a fairly good properties for design target (power levels indication) - more over the inverter passed the basic logic test without any modifications (this is like something extraordinary)

and the schmitt+inverter itself with SB captured 2-ch scope diagram through 1nF+3.6kΩ decoupler-probes

if you remove the 15pF capacitor and add input diode pairs you'll have a set of 7µA NAND-s
