I was reading this discussion - Interlock Discussion, because I want to design a Half Bridge MOSFET driver, with interlock. I recreated both the circuits in LTspice that were recommended The logic I want is - In1 In2 Op 0 0 both OFF 1 0 Up MOS ON, BOT MOS OFF 0...

I'm trying to make a VCO from this schematic but I can't get it to work. My oscilloscope broke so I can't use it but when I plug in my headphones I only hear a slight DC voltage. (The circuit runs on a single supply)

Hi everyone, I won't bore you with background but I've been working on this for a long while and would love some feedback on it's efficacy. It's the first major circuit project I've ever undertaken, you guys seem nice but still I'd appreciate if you could keep that in mind. As stated in the...

Hello, First of all, which company's ICs should I look at, Texas or Analog? I want to design a synchronous buck converter to deliver 5.1 VDC at 3 A maximum to a Raspberry Pi 4 B via a USB-A port. My power source is 24VDC from a power supply at 230VAC to 24VDC. My first choice is the LMS3655...

You are provided with a 230 V / 50 Hz ac supply, a 6-0-6 centre-tapped transformer and a BJT of dc current gain 150. Biasing the transistor using a supply of 5.6 V (develop your own), (i) design an amplifier of voltage gain 200 i have designed could anyone correct me design as follows Av=200...

general qn how will the circuit act to this will d1 be open ckted can anyone help i am using oa79 diode breakdown is .3

Given a zener of 4.7V with a knee current of 1mA and a maximum power dissipation of 1W . Design a regulated power supply to deliver a load current ranging from 0 to 50 mA. Given an AC Supply of 230 Vrms , 50 Hz . Design an auxiliary Circuit which gives an output ranging from 8 to 8.4V i saw...

Hello, I am working on my Design AM transceiver system project. In this project, we are prohibited from using other integrated circuits except for the 555 integrated circuit. In this case, how can I do signal modulation and demodulation without using opamps and similar integrated circuits?

hello, I have an analog electronics exam, and i hope that someone might help me understand the course thank you.

Nothing’s more frustrating than building an analog circuit and getting unexpected noise messing with your signals. Whether it's hum, interference, or random glitches, noise can be a real headache. Here are some practical tips to keep it under control: Keep Your Grounding Clean – A poor...

I am attempting to use a vintage Keithley 610C electrometer and want to make sure I'm using the proper adapter to get from the UHF input to my triax cable that has a BNC connector. My triax cable is the Triax (M), 3 Lug To 3 Alligator Clips...

Hello there, I've been try to learn how sigma-delta ADC works, I've been through the block diagram mostly and tried simulating one myself by following this video lecture from "The signal path" channel, the wiring is right as it shows in the circuit diagram( from timeframe 34:30 ) and it also...

I was going through the comparator topic and realised that it merely compares the input and the reference voltage. Is it necessary to use resistors along with the inputs in such a circuit? I cannot find any effect of these resistors on the circuit or the output yet it seems to be an elementary...

Hi all, I have this IC which creates a linear voltage ramp proportional to the input voltage based on the capacitor on the output in parallel to ground. I then have to do some analog computation using op amps. When I connect the output of this IC to an op-amp, the ramp is ruined. Is there any...

Hi, Looking for a 5 bit ADC but at the moment I can only find 6 bit ones online. Anyone know where I might be able to get ahold of a 5 bit ADC? Thanks!

Hi everybody, I'm taking a beginners DC circuitry course and I'm trying to learn on my own time about analog circuitry, something which has fascinated me for a while now. One of the things I'm trying to start with is, as the title states, a voltage follower, since this is (supposed to be) a...

I have a steel container utilized for beer fermentation, housing an iSpindel hydrometer sensor immersed in the liquid. This sensor transmits data through 2.4GHz WiFi. To enhance signal strength outside the vessel, would it be beneficial to affix two passive omni 2.4GHz antennas to the lid...

Is there any resistive humidity sensor that I can power with a dc voltage and with analog output not digital? I prefer araw sensor not a module.

Hi, On my board I am using SPI slave devices in the following configuration. when every there is an spi communication happening between controller and slave1, everything is good. whereas, during the communication between the controller and slave2 SPI_CLK line is dipping from 2.4 to...

I am using one machine (which has a small motor) which has battery of 1.2v which got dead and i want to change the power source to USB. The battery is of 1.2V and 400mAh. Motor connected to works perfectly fine if provide the 1.2V from bench power supply. I want to use USB power supply instead.
