## How to achieve Vref changing with Vdd

In the circuit, I want to compare the voltage reference Vref and source voltage Vdd. It is necessary to make Vref change with Vdd, which means a constant voltage is supposed to connect between this two voltage. But I have no idea what structure can achieve this.

## Low and high impedance of low pass stepped impedance filter

Telephone companies found it practical to make 600 ohms a standard in various types of circuitry, equipment and measurements, going back decades. Thus 1k ohm or less is regarded as low impedance. dynamic microphones can be included since they typically are several hundred ohms. It's a relative scale for considering low versus high impedance. Each

## Using Linux on ARM A9 cortecx

Hi guys, I have the DE1-SoC having cyclone 5 with the ARM A9 cortex, but I will be using the ARM to boot Linux and do python programming. Currently, I have a problem that I can't open the GUI via the VNC viewer. The manual I am using is

## Broad band dsign of LNA best topology

I want to design LNA from 12-18 GHz. I want to get s11 and s22 less than -10 dB. Which are the best topologies for obtaining broad band LNA from 12-18 GHz. Can you guide to obtain S11 and S22 less than -10 dB from 12 to 18 GHz.

## Updating footprint in PCB window after being changed in PCB library

Hello, I designed my board in Altium designer. After checking the DRC I had to change a clearance in my PCB library. Howeve after doing that, updating my schematic librar and schematic, there was nothing to update into PCB window( it means changing a size,clearance, ... in PCB library which nothing else (such as numbers of pins , ...) happens wo

## Changing room and component positions in Altium

Hello, Here is my PCB file. I need to know why P1_1 and U2_1 don't move by changing their room position. In addition by selecting all components again, they don't move.(ROOM name :TCP1) Thank you.

## [moved] What is Cadence genus synthesis, report power?

I have written a verilog code of a counter, and I have done the synthesis of that counter code using Cadence Genus tool. Now I want to calculate the power. For that I have used the command report power and got the leakage power, dynamic power, mainly total power consumed what I actually want. Now my question is whether this p

## [Cadence ADE XL] Optimize a Common Source Amplifier to 15dB gain via Corner Analysis

Hi there I'm a student intern, very new to ADE XL, with basic knowledge of Analog IC in Common Source Amplifier Characteristics. I am seeking some help in some guide in using the Corner Analysis / Optimization tools in ADE XL. Firstly, I need to optimize a Common Source Amplifier circuit as shown, with one single bias point, Vindc, maintain

## Noise calculation in static-dynamic circuit

Is there a way to calculate the input referred noise of a circuit that contains static sub circuit followed by a dynamic sub circuit??

## PCB Christmas tree Ornaments

Hi, I would like to create a christmas tree ornament consists of a few LED's (no more than 20, maybe even 10/15). It needs to be light weight, but I would also like it if it would last long. After all I don't want to change batteries 3 times a day. But I also don't want it to be ridiculously expensive as I'm going to hang multiple (5/10 piece

## 1200 baud data transfer over audio passband of cellphone. Is that possible?

1200 baud data transfer over audio passband of cellphone. Is that possible through the use of their codecs? Has anyone actually tried it? There are videos about comms on 300 baud but how about 1200 baud, has anyone ever tried it?

## LED forward voltage for 700mA LED at 350mA

The figures look reasonable per junction but many higher power LEDs have several junctions in series. Also consider that the dynamic resistace of junctions add together too so you should expect more Vf variation with current for multi-junction packages. Brian.

## CST Studio Body size outside of dynamic range of 3D modeler

I am modeling a structure but I get an error like "Body's bounding box exceed valid box. Body size is outside dynamic range of the 3D modeler". Some literature says that the Boudaris conditions on CST studio have to be set to "Open". I have tried that but it did not work. Any help? Thanks :)

## Pre-defined layer colors in GC Prevue?

Hi, Every time we re-do the gerber files for a PCB, (which is very often) we have to reload it into GC Prevue to view the gerbers. How can one load the gerbers in such a way that certain layers have certain colors? (eg top copper = red, etc etc). It takes ages to keep loading new gerbers, and then changing the colors to our color system.

## Dynamic Comparator noise using spectre transient noise analysis

I dont know how to calculate the input referred noise of a dynamic comparator using transient noise analysis in cadence spectre

## Rookie making an audio step-up transformer

Hello everybody! -(sorry if this is a duplicate, the first post did not show up in the forum for some reason)- I've recently (re-)started my journey in electronics. Last time I tried was very long time ago though. I started with books but not everything I read I understand. So I started playing with an amp for a dynamic mic and then I read
