Questions tagged [ringing]

Anything related to ringing, i.e. a phenomenon arising in some circuits when the output signal exhibit damped oscillations superimposed to its steady-state response when reacting to an abrupt variation (e.g. a step) of its input signal.

What is causing large oscillations in my DC/DC boost converter? Is this ground bounce or some other effect?

I designed my first PCB for a DC-DC boost converter only to find that it produced very noisy output. The design is based around the MIC2253. Here's a schematic: Although my circuit allows for different combinations of input voltages (Vin) and…

What can reduce overshoot and ringing on a simple square wave pulse generator?

I've built a simple RC and Schmitt-trigger-based square wave pulse generator. On the breadboard, it has some obvious unwanted qualities due to jumper length, the breadboard itself, etc. Schematic and breadboard version: And the waveform…

Severe ringing when high side MOSFET in half bridge circuit switches on

I have designed a PCB (intended as a prototyping building block) that has a IR2113 high and low side gate driver driving two IRF3205 (55V, 8mΩ, 110A) power MOSFETs in half-bridge configuration: Picture of the physical setup Upon testing the…

High current buck converter has excessive ringing and poor regulation

I am designing a power supply to power two fiber-coupled diode arrays for a solid state laser. The diode arrays need a current controlled source of about 50 A and will have a voltage drop of < 2.2 V. The diode wavelengths drift with temperature so I…

Switching regulator ringing

I have developed a 48v -> 6v DCDC switching regulator using the LTC3810. It works well, except that there is some ringing on the output at each switch. You can see the 'scope trace on the picture. This measurement was taken across the input cap of…

Severe ringing when using high-level gate driver (HIP4081)

I am working on a project using the HIP4081 full bridge driver. I prototyped the working circuit on a breadboard experiencing heavy ringing on the gates of the high side MOSFETs (the ringing also shows up on the 12 V VCC of the HIP4081 supply). The…

Ringing on SPI square wave and other SPI issues

I've just started learning this material not too long ago and need some help. I'm trying to communicate with SPI from an AD7124-4 ADC IC to an ESP32. The first problem I'm having is I'm getting a lot of ringing on the square waves which is shown in…

Why are low values of resistor in non-inverting configuration of opamp causing gain peaking?

I am trying to simulate frequency response of TLV07 in non-inverting configuration for gain 10 as shown below: The frequency response shows peaking as shown below: It is worse for smaller values of resistors like 1 and 10: The response is…

Causes of ringing in a PCB

Im trying to understand the source of ringing at the termination point of a PCB traces before i delve into actually designing a PCB. For example, by 'termination point', I mean a clock signal terminating at the input of an IC. Some online sources…

SMPS, output ringing?

I built an SMPS (see here for details), and so far it's been working good. But I noticed a strange oscillation (or ringing?) at the output. Here's what it looks like, with a 4 amps load: Now, you'll see a HF oscillation when the switch turns on…

Best options for limiting input ringing with ceramic capacitors

Ceramic capacitors have this unfortunate property which can cause spikes in voltage when live batteries are connected to boards (hot-plugging), due to the inductance of the wires to the batteries and the very low inductance of the capacitors. It can…
