How does this ramp generator circuit work?
The circuit is taken from Analog Dialogue, Volume 3, March 1969, the article is titled Noise and Operational Amplifier Circuits. The circuit is a ramp generator, but I can't figure out how it works. ...

Constant ramp not behaving as expected in SPICE simulation [closed]
Looking for some advice on creating a constant (linear) ramp which meets a certain specification, I've designed this example which works well in ideal simulation but I cannot get it to work in SPICE. ...

Analog long duration timer (5 minutes) using a ramp
I am trying to make a timer with a period of about 5 min. The problem with such a slow ramp (with high impedance) is in triggering the next circuit like a latch or monostable to get a useful output ...

What can I do to get a stable bias on this current sink?
I am still working on trying to get a stable 60 Hz ramp generator with a down-slope, and I am trying to do it from first principles and as simple as possible to understand fully what I'm doing.
I got ...

Miller integrator ramp generator?
In a page on Ramp Generators I found this peculiar circuit which is said to be superb in its linearity. But I can't make sense of it. It doesn't discuss any of the actual R and C values.
I can see ...

LTspice and TTL logic gate parameters, my edge triggered ramp generator is current starved? How to correctly estimate TTL gate impedances?
Continuing with my edge triggered ramp generator and its simulation, thanks to all your help I have the LTspice simulation set up that I can see a theoretical circuit work that uses the rising edge of ...

What would be the simplest BJT based *linear* ramp generator?
Let's say I have a 74LS161 based counter, and I want an analog ramp generator which will linearly increase until the ripple-carry-output goes back down (so that the ramp goes up the entire time the ...
