Questions tagged [rise-time]
Anything related to the rise time of a signal. The rise time is a parameter used to characterize abrupt transitions in a signal waveform. It is usually defined as the time needed by the signal to go from the 10% to the 90% of the level it attains at the end of the transition.

How can I slow down the rise and fall time of a power MOSFET without adding a delay before the switching begins?
I'm building a simple 5 W HF CW transmitter, where the power to the final stages is controlled by a P-Channel Power MOSFET, whose gate is connected to a key.
I added a simple capacitor between the ...

Trying to figure out rise/fall times for different load conditions
I have a device that requires a certain rise/fall time for its input clock. It specs a .7ns rise and fall time with a 20% to 80% measurement at a Cin=6pf. I should note that the spec rise/fall time ...

Relation between rise and fall times and capacitance
So I'm currently reading the datasheet of the Motorola 68hc000 CPU and I want to be able to estimate how many devices I can plug to the bus directly before I encounter issues.
So first things first, ...

Rise time to an input
A device trigger input requires 1 V pulse (can stand up to 6 V) and has 0.5 V threshold voltage. Now if I apply a 5 V pulse with 10 ns rise time, how can I estimate the time it takes a rising edge to ...

Measuring rise time with spectrum analyzer
Is it possible to measure the rise time (range 100ps-1ns) of a square wave signal with a spectrum analyzer (my oscilloscope has 100MHz bandwidth only)? My model is Rigol 3030N (9kHz-3GHz).
My idea is ...

Constant DC load stability and bandwidth slewrate
For this circuit, how do I know if the rise edge was limited by slew rate or bandwidth? What's the effect of R2 and C2 on bandwidth?
-3db of this circuit in simulation is 649 kHz, I know in this ...

How to determine rise time from a datasheet?
I am trying to determine the rise time for a component in my circuit. I am unsure if my current method is correct and could use some verification. I would love help in the general case as well.
Case 1:...

Power Supply rise time and configuration
Reset managment:
from HW checklist and datasheet of USB2517 (page 48), is required a rise time for the 3V3 maximum of 400us. In our case it will be above 1ms.
In this case, is it necessary to use a ...

What happens if rise time specification is not met
I have a design where an NXP i.MX8M nano CPU has a KSZ8081RNAIA Ethernet Phy connected.
During prototype testing, we found now that the supply voltage rise time provided by the CPU PMIC (NXP PCA9450B) ...

In an RC circuit, how do you explain the fast rise of voltage at a point close to source? (Weak pull up)
In the above figure, the voltage at the intermediate point rises quickly whereas the voltage after R2 is increases slowly ( as governed by the capacitor voltage.)
I am not getting the intuitive ...
