Custom eXperimental 0.6 ... 1.6 V inverter

From back to forth --

32k768 Qz Driver ::

the interesting thing about this X-tal pusher is that the 1 single inverter most likely has a sufficient gain and speed to manage the task (if it's already oscillating) but using uneven no. of gates (1,3 were tested) and increasing the +feedback the oscillations start ubruptly at 100x to 300x higher fq. than the one of the quartz -- otherwise the quartz won't get into phase lock with feedback and thus won't collect the energy for start up ???
-- however the shown - an even no. of gates - v. has quite flexible tuning range where everywhere the oscillations do start e.g. the quartz gets phase locked with feedback and starts storing the energy . . . this is the first time i encounter such . . . curious ?

another 32768cps osc.

the resistor values can be varied** from R.c ~50k(perhaps less) ÷ 4M Ω , increasing the X-Tal coupling capacities (keep Qz→Base > Qz←Collector better result in most cases) boosts startup also degrades waveforms , increasing R.e shunting capacities gives better fq. responce below the target fq. (it likely dosent boost startup) , adding C-R chain from base to ground kills some unwanted amplification ? improves waveforms especially I.qz ? adjusts/stabilizes the osc.fq. (it takes a lot of playing around to specify the type of oscillator better - i just found such frustrating at this time) -- the main point -- it uses trivial & flexy range of capacities !!! ((if you dont much change the C8,9,2 - the operating power / other component values  - can be widely modified**))

the prev. v.-s ::
32768kHz Qz-resonator osc. test-dev.

32768kHz Qz. Resonator Osc. test/dev.

shortly i need to build a fq. counter coz the 1 built in in KYORITSU KEW1018 . . . "is not too fun to go"
to conduct some IR Comm and other strobed-LED experiments

for that we need a time setting oscillator that's fq. can be fine tuned . . . dev. snap-sh's

the LM4250 or К(Р)1407УД2 (actually what i got) seems to be a tricky thing to set up right - it'll take a number of real world tests before an attempt to connect it to anywhere ...

blah blah blah . . .

there's some shit with setting up the LM4250 model ::
.cir - file :: LM4250.cir ◄ .include LM4250.cir
.asy - file :: LM4250_NS.asy ◄ [F2] or Insert New Component
Component - Value :: LM4250/NS ◄ . . . the 3-rd variant of naming your LM4250

2015-08-17 :: the LM4250/KP1407yg2 is actually quite easy to use (you only have to pre-balance/-offset it) if you use a component level model
