    Where to study analog layout design (+ interview question)

    Hi everyone, I applied for a job as layout engineer. The job spec are the following: DUTY: -schematic to full custom layout translation -layout verification and DRC -floor planning for optimal die area -generation of wire bonding diagram for assembly approval before the tape-out REQUIREMENTS...

    [moved] Difficult to move toward my right job (ASIC, RTL/Physical Design)

    Yes, guys, you hitted the point perfectly. Even I dind't write it in the OP, I know that the underlying problem is the self-realizion, the problem with this system that kills creativity and initiative, that makes the persons a 9-6 slaves killing their enthusiasm and thus their productivity. And...

    [moved] Difficult to move toward my right job (ASIC, RTL/Physical Design)

    Re: Difficult to move toward my right job (ASIC, RTL/Physical Design) Hi Bradth, hi mitra, thank you for the reply. I prepared this reply when this thread was in EDA Job section, but I wasn't able to reply there. You are for sure right, but I have to explain better that the working situation...

    [moved] Difficult to move toward my right job (ASIC, RTL/Physical Design)

    Hi everyone, I need some advice because my career, that is at its beginning, is already stucked and I'm so frustratin. I'm italian, and here the university have a lot of theory; we student have really nice and deep theoretical knwoledge, even in Engineering degree the amount of science is really...

    [SOLVED] Newbie of MPLAB X. Led blinking with PIC32MX

    Ok I do it and now it are included. I include every .h file in "header file" section and every .c file in "source file" section. Hope it is right. Thank you

    [SOLVED] Newbie of MPLAB X. Led blinking with PIC32MX

    The main question is solved. but I have another question that concern the fact I'm a newbie with MPLAB X. I want to use the fatFS library. This library contain many file, that I put in the main directory where is the main.c. Among this file there are ff.h, that contain the declarations of the...

    [SOLVED] Newbie of MPLAB X. Led blinking with PIC32MX

    Thank you for reply for making the #pragma code, I do the following in MPLAB X: in the top bar menu, Windows -> PIC Memory Views -> Configuration bits. This show a menu identical to the mikroC one. I just set the value and click to "generate source code" to produce the relative #pragma code...

    [SOLVED] Newbie of MPLAB X. Led blinking with PIC32MX

    I have disabled it and retry, but nothing is changed. EDIT: the strange thing is that the LEDs blinking faster than expected, not slower, even I set the maximum speed for sysclk and pbclk. Also I don't think I'm wrong in #pragma setting, because the setting is exactly egual to those I used in...

    [SOLVED] Newbie of MPLAB X. Led blinking with PIC32MX

    Hi everyone, I have just moved from mikroC to MPLAB X IDE with XC32 programmer. I'm trying to make the simply LED blinking code. The problem is the blinking is faster than expected. This is the code: #include <p32xxxx.h> #include <plib.h> #include <stdio.h> #include <stdlib.h> #include <xc.h>...

    [SOLVED] Conditioning circuit for microphone

    Because other section of my circuit needs dual supply (-+ 5 V ) so if there are any advantages using dual supply in this OP AMP, I can do it EDIT: I attach the data sheet of my microphone. I don't think the amplifier inside is a simple pull up JFET, but a real amplifier; in this case R1...

    [SOLVED] Conditioning circuit for microphone

    last question: for other reasons, in my circuit I must use a dual supply. So, it is convenient to convert the circuit with dual supply instead of single supply or it is indifferent?

    [SOLVED] Conditioning circuit for microphone

    Yes my signal is mono and I thought at the same solution, first OP AMP for preamp and second for buffer. Thank you!

    [SOLVED] Conditioning circuit for microphone

    ah ok. Now I understand. so in the single supply mode (with ground at V- pin) there isn't rail to rail problem for lower voltage? I understand right? so I will use a buffer Thank you very much

    [SOLVED] Conditioning circuit for microphone

    What is the porpouse of the final 3.9k resistor? Since the ADC of my microcontroller require a low input resistance for keeping low the sampling time, can I put a buffer between the output of your circuit and my ADC? or in this circuit the output resistence is already low enough? A 0.6 V start...

    [SOLVED] Conditioning circuit for microphone

    very usefull comment Audioguru, many thanks. I'm a newbie about analog design, because my education focused on digital design and microelettronics. It's ever a pleasure to receive suggestion from experts. The fact that the max output is reached only with very loud sounds is logic, but I didn't...
