a primitive VCO #hardware #simulation. It runs at about 15MHz, varying monotonically with an input voltage. It consists of three NPN transistors and nine resistors arranged in an inverting Schmitt trigger with a feedback path through a 1K resistor to a 100pF capacitor on the input. Upon reducing the capacitor to 5pF I get about 260 to 320 MHz. My objective here is to design a minimal VCO I could actually build, without worrying about temperature compensation or linearity, for use as a high-speed ADC, correcting the deviations in software.

this version of the VCO #hardware #simulation varies from 174MHz to 226MHz as the input signal varies from 5V to 0V. It uses a 47pF capacitor on the input (which has a 5kΩ resistor on it) and just lower resistance; none of the resistors are over 1kΩ. If this works in real life, sampling the counts at 1 megasample per second would give you counts from 174 to 226, and thus almost 6 bits of precision, though with no guarantee of linearity or invariance with supply voltage or temperature. (And indeed it doesn't work at all at 6 V, and gives much faster oscillation at 4 V.) Short URL https://is.gd/fastvco

The #HARC folks, including Jonathan Edwards and under the leadership of Alex Warth, are working on projects including a visible programming environment called Seymour, a JS-programmable visual environment called Purple, a parser generator called Ohm, a spreadsheet for writing apps called Chorus, something called Trainee I don’t understand but which has something to do with planners, and a programming-by-demonstration environment called Transcript. #explorable-explanations
