Test concept 2 for Jj

This time, I changed her parents species and removed her semblance (so it wouldn't be like Grimm because I didnt want to make Jj similar to Grimm, more or less just give Jj her own characteristics)

Input current measurement (IIL/IIH)

In this post I will talk about the Input current measurement (IIL and IIH) and propose a solution to measure it.

IIL and IIH

This is the capacity of the chip to absorb the current in input. Maybe you can think it’s not really important because the output technology can drive a current up to 10mA.

That is right in most of the digital chips but it’s not so simple for mixsignal, RF and…

Click here to know how to make a continuity test on J750 (3.50.50)

In this post I will show you how to make a continuity test on J750 with the template. In the first part, I will show you how to make the test with the DPS and in the second with the PMU.

Continuity Test for DPS

For this test I will use the PowerSupply_T template. See below the instance sheet

Example of Instances sheet with continuity test

To edit the template right-click on the name…

Click here to know about the Intermodulation test (IMX)

In this post I will tell you about the intermodulation test and how to make it.

What is the intermodulation?

In this test, we will capture a signal with a modulation. A modulation is a signal with 2 frequencies, one is the carrier and the second the signal to modulate. In this case we will use a modulation of the amplitude where the carrier is f1 and the signal will be at Δf = f2 – f1.

T…

Click here to know how to calculate the Differential Non-linearity (DNL)

In this post I will explain the goal of the Differential non-linearity (DNL) and how to calculate it.

The goals of the differential non-linearity

The differential non-linearity gave the information about the gain of the ADC. More precisely the linearity of the gain through all codes.

How to Calculate the DNL

First of all, you need to generate a ramp with, at least, 2 times the ADC…

Click here to know how to calculate an Integral Nonlinearity (INL) on an ATE

In this post I will try to give you some explaination about the integral nonlinearity INL and how to calculate it.

The goal of the Integral Nonlinearity (INL)

The INL or Integrale nonlinearity verify the shift of the code on the output against an ideal ADC.

Measure the maximum INL

First of all you need to have a ramp of value with a minimum resolution of twice of the resolution of the…

Click here to know about the Missing code test

The missing code test is used to verify if the ADC can provide all the code possible for its resolution. I will explain the goal of this test and how to make it.

The Goal of the Missing Code Test

As I said this test verify if there is some missing code in its resolution. This test is to do before the others because if a code is missing the calculation of the INL and DNL will be false. So…
