How to control DAC white noise at increasing sample rates?

A lot of background, the question is at the end: I have made some simulations and experimental tests with the goal of achieving lowest possible noise floor using DACs with a sample rate of at least 200 kHz (BW ~ 100 kHz). Specifically I want to…

How do you fix the glitches in the following Karnaugh maps?

The following circuit is supposed to output 1 if the input is greater or equal than 1010 (decimal 10). The truth table is given and we are supposed to convert that to POS and SOP using Karnaugh maps. Here's the truth table with the minterms and the…

Treadmill causes nearby electronics glitch

I don't know if it is right place to ask, if not correct/guide me. I recently have built treadmill workstation, where I could walk and work (rather than just sitting). But as soon as I turn on treadmill, nearby keyboard, mouse and monitor starts…

STM32 PWM and Output Compare

I have some simple firmware written for an ATmega328 (not Arduino) and I'm converting to STM32. I have more than one STM32 development board, so for now I'm searching a generic config and generic code. The original firmware generates PWM (duty cycle…

Glitches in clock gating cell

how exactly does glitch happen for rising-edge and falling-edge ICG ? Why for the top version of rising-edge ICG, there is no X at the MSB of the latch output ? Note: TE signal is asynchronous to CLK, and see also the red 0 and 1 at the output

Changing pin direction without glitching on LPC800

I'm looking at an LPC812 Cortex M0+ microcontroller and its GPIO functions. On a PIC microcontroller, one would always set the LATch prior to changing the direction of a given pin. This avoids the possibly nasty situation where a pin "gitches". ie:…

A problem regarding my Slayer Exciter circuit?

I have made a Slayer Exciter circuit for my school project. I'm going to be assessed on it. Now, it works just fine. But if I have to light a tubelight or something, I have to touch the terminal to the wire sticking out of my secondary coil. Then I…

For oscilloscope, what are the differences for Glitch Capture Channel and Sample Channel?

I'm using a Tektronix oscilloscope and I use only one channel. I export the data for that channel to a csv file and open it on my PC. I found the csv file actually contains data for two waveforms! One is called Glitch Capture Channel, the other is…

How to get rid of glitch?

I have designed simple P-channel MOSFET circuit. It works well, but when low source power is applied (1 V), a glitch occurs in the output signal. I tried R, L and C component, but it didn't work. What can I do to get rid of this? In fact, the…

Determining cause of QSPI FLASH output glitches

I am testing a QSPI NOR FLASH device on a board I designed. It's datasheet is here. Although it is working, I am seeing some glitches on the FLASH SDO (Serial Data Output) line. All other signals are inputs and look fine. I believe it is working…

Getting glitches on GPIO using a MOSFET as a logic level converter

I need to connect an Event Detection pin (pin of the NXP NTAG 5 component) to a GPIO of the NXP i.XM6 processor. The problem is that the NTAG 5 pin has a logic level of 5V and the GPIO has a logic level of 1.8V. So I used this N-Channel MOSFET to…

Reasons for glitches observed on PCB from physical touch of floating enclosure

I have a circuit on a PCB on which I’m observing “analogue glitches” when making physical contact with the enclosure. This enclosure is from ABS and there is a circular connector on one side for supplying USB power on the enclosure connected to the…
