Hello, I am designing a CMOS receiver circuit. I have a few doubts regarding the LNA and mixer design. 1. In LNA design usually the cascode transistor's width is kept equal to the main transistor's width. this is done so that the source of the cascode transistor and the drain of the main transistor can be merged into one, which reduces the noise
Hello, I have to find and simulate a simple IR transmitter and receiver circuit. But these circuits should not contain any IC's such as 555. How can I find these circuits? Can u pls give me some schematics links? Thanx for help.

Can anyone suggest a GPS receiver circuit or chip that is easy to implement. right now i'm planning to use the MAX2742 + CXD2932 chip but I think the CXD2932 cost much.
Hi guys, 1st of all thx for taking your time. I'm now doing a project on IR sensor, and i would like to combine two IR sensor together(including two sets of tramitter and receiver), i'm going to link the two receiver circuit together to work with XNOR gate and a buzzer. In the sense of once there is only 1 receiver detect (...)

hi i need fm receiver with usb connection and remote function circuit diagram with part list anybody have pls give to me.........
hey guys i need help designing a very simple rf circuit. i wanted to make a simple transmitter that would be fairly compact and has a switch. on the other side there would be a receiver that will turn on an led once the button is pressed. it's for a short distance so range is not a problem. if anyone could provide a schematic that would be awesome,
Hi all! I want to build a simple AM receiver in the 30 MHz range. It's for a hobby project so the requirements might seem strange but it needs to have quite good selectivity for nearby disturbing signals. What would be a good topology to use? I think it would be wise to go for a superheterodyne receiver in order to be able to design a selecti
plz take a look at the following link : AM receiver the last 3 lines in the first paragragh say : "however the input signal levels at RF are tiny, typically 50uV appearing across the coil being amplified by Q2 and being about 5mV RF across the 2k2 load resistor ". my question
Hello, I need the circuit diagram of radio frequency FM Transmitter receiver which have the range of 50 feet of data transmission. Please give me that type of circuit diagram if you get it..
Hi, I'm planning on making a small home automation board which would connect to lights, motors and wireless. My problem comes with wireless because I'd like to make a small wireless receiver circuit that would receive datas from the board in order to light a computer. I saw many receiver/transmiter posts but they look way different from (...)
hi...i want to know abt the circuit diagram for the ir receiver using "k4" IR reciever...i am uploading the pic of the reciever i am using...helpp..:cry:!!
i want to make 2.4 gh receiver ,,, i really don't know what to do is there is away that i could change the circuit of router to a receiver or is there is circuit ,,, or should i decrease the freq is so to which freq
I developed a wireless system with an MSP430 and a cheap receiver/transmitter pair. You can get them for about five bucks on amazon. I think I used this one. With this setup I was achieving about 20 ft communication with no antenna and o
I wanted to know the function of pie attenuators when they are in the receiver portion of the circuit. thanks a lot
I want to make a powerful FM radio/ receiver without any noise. It's for my electronis project. I learnt that TDA7000 is a bulit in IC for FM receiver. But I need more information and specific circuit diagram for a noise free high amplifier radio device. help me for making it. Thanks in advance.
You need 2 different receivers for different transmitters. HT12D cannot differentiate between two different transmission data. Both data received by a single 433mhz receiver will be mixed up. You can use single receiver only if you can make sure any one transmitter transmits at a time. Working on single frequency but with (...)
Hi! How do I build a R/C receiver for 40MHz? Any good links or other information? I had a Hitec 5-channel receiver that gave up... Does anyone perhaps have the schematic for it? (HY-5RN) Thanks! /Janne
I have designed a sensor in which light from LED (main) is detected by a Photodiode (PD). The received signal is then filtered and is made to flash an LED (indicator) when the received signal goes above a threshold voltage. The main LED is driven by a 500 hz pulse signal. This whole thing is built as one unit. Now I want to separate this into two p
Hi there Dear friends I need a sensitive Am reciever circuit (demodulator) circuit for demodulating signals that modulated machanically by Doppler effect and recieved by a piezoelectric transducer at 2Mhz and amplitude about 10 mv. Please Help me thanx
Hi all!!!! I need to construct an ultra low cost (less than US$2.50) transmitter. 0dB output power, OOK modulated, stable (maybe SAW stabilized), 433 or 432 MHZ, 2.5 to 3.3V power supply. Need only the Tx circuit (the modulation signal comes ready from another circuit). Low power consumption is a need. Could anyone help me with circuits (...)
Hi, all, I got a project that require me to design RFID ISO14443 TYPEB PICC receiver circuit by TSMC 0.35um process. Since I am a new comer in this area, it will be great help if you, my friend can contribute any exsited CMOS circuit for this topic. My requirement is below. Thanks in advance!! Raymond
I have been working on an 8MHz piezo receiver circuit using a high-impedance FET input buffer followed by several common-emitter amplifier gain stages...but it doesnt seem to work no matter what... FET followers, according to 'Horowitz and Hill' have rather high output impedance so I've resorted to emitter followers instead. No joy. Is there
I'm working on a simple receiver circuit. Just to receiver a 27MHz signal to drive a motor. This is how the circuit goes.. Tuned circuit ----> Amplifier ----> halfwave rectifier ---> transistor as a switch to drive the motor When i only tested the motor circuit itself... just using a (...)
i have a 433mhz receiver module, some pins are connected to 5V and GND, one of those pins is the output, i have connected this pin to an oscilloscope and only i can see noise. How can i eliminate this noise, i want to see the code of a garage control for example. Sorry for my English.
Hi, Is there anyone expert in this area Or any good reference? Thanks
I am a newbie in electronics.. I have been trying to build a 4 bit remote control for different applications in toy cars etc.. i used MC145026/27 encoder/decoder pair to generate the signals n all.. they work perfect when connected directly with each other.. but im having problems in making tx/rx :(.. i used the 433mhz design uploaded here.. unfort
I have a AM HIRK 433mhz receiver and when I'm transmitting signals to it the range is only about 2m compared with 80m as stated in the datasheet. I have been using a 1/4 wavelength antenna, and have changed to a 1/2 wavelength antenna. This is slightly better but only about 7m. Has anyone got any ideas as to why this is so?
I would like you to send me an infrared transmitter receiver circuit with relay outputs. I have tried a design using LM741 and LM567 on the receiver side with one relay, it works okay. But now, I am required to have two different relay outputs. You may include the PIC it's okay.
you can receive form 20 mhz - 90 mhz by this circuit
Hello people, I hav constructed one DTMF based Fm transmitter circuits successfully.. Now for de-coding it i need a Fm reciever.. I tested my transmitter with a commercial radio.. Its working pretty well at around 99 MHz.. I want to construct a reciever circuit myself.. So if u hav good working circuit or any link to a good Fm (...)
Can any body suggest a good FM receiver ICs (like cxa1019) please.. Will be helpfull if you can suggest some.. Is cxa 1019 itself good?? The data sheet of this ic is in chinese(with some english)..
