Analog circuits have a range of voltages, rather than just two as in digital logic.

What is the input impedance of a differential amplifier?
Since this question is high up on google searches, I think an answer that fleshes out Andy aka's (correct) answer with the corresponding theory that explains the intuition and simulations could be hel …

Passive linear circuit to generate high-voltage spikes from a 10 V peak-to-peak square wave
If you use passive devices, you're essentially limited to RLC (and some other things like diodes). Here are ways you can implement the different parts of the design. It sounds like a homework assignme …

BJT in saturation mode equations
You kind of don't need too many equations. Look at the datasheet to get Vce,sat and Vbe,sat - then make those the junction voltages. Then solve for currents and voltages. So maybe Vbe is 0.7 V and Vce …

Understanding high-speed Improvements to discrete BJT multivibrator
I believe it's providing a path for the stored base charge to discharge. Basically turning the capacitors into "speed up capacitors" in addition to timing caps. It could be good to plot the current th …

Inductor datasheet Frequency question
You typically would like to be operating at <10x below SRF. When you're at <10x SRF, the inductance is pretty much the nominal inductance. As you approach the SRF, inductance increases - but you'll ha …
