Hello, I'm an electronics engineering student, currently trying to design a circuit that includes a transformer.
I'm using Orcad's Capture (Pspice) software.
When I searched "Transformer", this part appeared as 'Generic Transformer', the part name goes by 'PWMXFM'. It has 5 connections, I...
Hi, I want to study about BJT Common Emitter Large (or bias) and Small Amplifier Circuits.
My question is I could not find a decent sufficient resource neither from youtube nor from google. :(
I want to study about those common emitter large & small signal models, analysis, ac gain, input &...
I need to design a summing amplifier with 2 inputs.
My input one is a DC voltage source of value 1.6V and the second one is a square wave whose amplitude is 5V and max frequency is 1Mhz.
The requirement is when the square wave is LOW(0V) the summer output should be 1.6V and when...
I was studying about adc basics from this document(ADC BASICS) .I have a question regarding the throughput calculation.The document says
"Consider the case of single ended conversion where one conversion takes 13 ADC clock cycles.Assuming the ADC clock frequency to be 1MHz, then...
I am designing LPF based differential demodulator(LPF_DDM) to retrieve differentially modulated signals, which are on-chip capacitive isolated [shown]. LPF_DDM includes a differential amplifier, LPF, and Schmitt trigger. I designed a two-stage opamp [specification below], as a...

The subject is to make ro=500k, ID=100u by setting VG3,VG4 and W/L of MOSFET.
And I got the exact values from Hand-calculation, and am trying to test it by using LTSpice.
I did make this schematic. and DC currents of two mosfet was around 74uA (I don't know it is right way to...
I need some clarifications for a non-inverting comparator design. I am using TLV7031 from TI.The circuit configuration is given as shown.
In the datasheet it is given as " When VIN is low, the output is also low. For the output to switch from low to high, VIN must rise to VIN1 ".
I am designing a clock distribution network using LM7171. This opamp is used in the non-inverting configuration with a gain of 2. My input clock frequency is 2.4Mhz, Amplitude is 3.6V.I can see glitching at the output. May I know where I went wrong?Please find the circuit diagram...
I have designed an LPF demodulator. In a normal situation it's working fine, however when i carried out the Process corner simulation, the threshold voltage of MOSFET changes which is obvious, due to which MOSFET's operation region changes, ultimately change the output.
My question is ...
I want to use gas flow meter. I checked for some sensors which have given measurement in ml/min and some has in ml/min.
I tried to convert the ml/min to m/s on google but got the result in m3/s.
I am not sure about the flow measurement and units used in the datasheets.
Is there any explanation...
I'm currently working on this circuit and I run upon this question which I'm not sure I understood it correctly :
For starters I have these values below - UCE=5V
Given formula rBE≈40mV / IB
First I calculated CE with the use...
Hi guys, Im fixing my communication board called :
CENTRAL LIGHTSYS RP432M00000E
and I found this device (see in the photo) is unattached /disconnected .. what type of this device? it sounds like capacitor but there's no symbol for if it's capacitor or whatever .. (there's nothing written on...
Hey, I'm new to electronics, and for one of my projects, I'm supposed to design an Ultrasonic Rangefinder using Analog components only!
The components include the 555 timers, SN74HC chips (specifically the 4 bit counter), 7 segment display and etc.
Most of the guides I have found online use an...
I was trying to study about bootstrapping in electronic circuits.
When I checked in Internet Wiki says it is a method to improve the input impedance of an amplifier.
In the power electronics context, it has another...
I have a question, please guide me and make me correct regarding MOSFET model selection? Although I used ‘nmos4’ both for 3.3V and 5V Vdd (supply voltage) in my simulation(cadence Virtuoso 6.1.6-64b), in both cases, it works fine and gives same results (according to my observation). So...
I am demodulating a signal. In which Low Pass Filter (LPF) is used to attenuate high frequency modulated signal. The input and outup of LPF is shown. The problem is the edges of LPF output signal is not square [as shown in figure] which result in poorly selection of lower and upper...
