Comparator IC IN+ changing after voltage divider
I have a battery that is charged to about 6.85V, this is the "batteryvoltage" input. Due to the voltage divider on IN+ I read 1.7V at the comparator. But when I plug in a separate wired 12V ...

Parasitic capacitance of high-speed comparator
I simulated an LM119 high-speed comparator and built one on a breadboard.
May I ask how to increase the frequency of the square wave produced by adjusting the resistor's values instead of reducing the ...

Relaxation oscillator issue, comparator self-oscillating at 25 MHz (40ns propagation delay)
I have a relaxation oscillator circuit which is supposed to oscillate around 6 MHz. It mostly oscillates in a very stable manner around that frequency.
Sometimes, however, it starts to oscillate at 25 ...
