I am currently looking for a number of Engineers across all experience levels to come join our industry leading semiconductor company.
We are looking for:
Senior Analog Design Engineers - 4+ years experience
Staff Analog Design Engineers - 8+ years experience
Principal Analog Design Engineers...
Dear Team,
I am using AMC1350 in one of my application. Please see the below circuit.
You can see that the voltage at the input of AMC1350 is 2.294V
The expected voltage at the input of AMC1350 is 2.3766V
I believe the loss of voltage at the input of AMC1350 is due to it's input impedance of...
We are measuring the voltage of a charger using the below circuit with the help of an ADC present in a microcontroller.
The value of charger voltage is required for some other applications. The value of charger voltage is used to calculate isolation resistance.
I tried to calculate the input...
Hello Fellow Electronics Enthusiasts,
I have a couple of AD822 single supply op amps. I wanted to clear one thing that is if i connect both the inputs of the op amp to the ground i still get a voltage of 5mV at the output. Is this normal or is there a problem with my ICs. Should the voltage be...
Hello Everyone,
If someone can help me to understand how to calculate the hysteresis of the Schmitt trigger-based NAND gate? Which MOSFET's dimension decides the Vth_H and Vth_L?
Thanks.
Hi,
I would like to read a sensor (acs712) a number of times (20), add them all up, then divide them by the number of reads. So I can get an average. to give me a sort of analogue "debounce". Am I guessing the sum function? I sincerely appreciate any advice you can all give me, I'm incredibly...
Hello,
I would like your suggestion on my first design Differential signal modulator [simulation attached].
Before jumping into design let me highlight my objective. I am differentiating a control signal of 1MHz and then modulating it with carrier frequency 15MHz(not limited to this specific...
Hi all,
I am very new to the field of RF so excuse me if my post is not the most detailed.
I am tasked with creating a circuit which automatically switches between two antennas. In this case Antenna 1 has precedence, if it is plugged in it should be the priority, Antenna 2 is a back up and...
I want to know if it is possible to model a photodiode InGasAs panchromatic PIN , in accord with datasheet, in simulator SPICE MicroCAP 12.Because the supllier where I boughit it has not a SPICE model.And if it is possible, which are those steps. Here it is data-sheet...
Hello there,
Nice to meet you!My name is Dragos.And I am a beginner in electronic and electrical engineering.I want some advices from you.I want to learn simulation S.P.I.C.E., using Mcro-CAP 12, or any profesional program,and I want to know how to begin the process of learning.I want to know...
Hello,
My name is Dragos. I am new in simulation S.P.I.C.E. an I want to use simulator Micro-CAP 12, to simulate some electrical parameters from some electronic components.
From InGaAs-photodiode IG17, I want to measure graphically follow electrical parameters:
-spectral response;
-dark...

Hi, i am new in analog designs. Now, i am trying to design a circuit using STC(Schmitt Trigger Comparator) circuit to monitor the voltage level of a car battery which normally is around 12 volts. Im trying to use two LEDs,green and red, to indicate the voltage level of the car battery. If the...
Hello,
I am working on a DIY project to interface a lot of signals to a NMEA2000 bus to be able to controle an older analog engine and other sensors with a new multi function display.
To do so I am using Arduino / Teensy microcontroller together with a NMEA2K library. I started to design the...
Hi, I am trying to power a Piezo Buzzer between 3.3VDC and 5VDC.
The voltage is being adjusted so the sound is low (at 3.3VDC) and loud(at 5VDC).
My attachment can be a little misleading. Alarm_low doesn't suggest the volume is low, just the number of beeps. Same holds true for Alarm_medium...
Hi, I am planning to build a FM transmitter for my school project. There are a lot of designs available on the internet and I simply don't know which to choose. I decided to choose a simple one from the cryptomuseum webpage. Its circuit is shown below.
I am new to RF design. Please forgive my...
