Some time ago I had similar problem. Finally I have decided to increase volt level for transmision. This solution I have finished on the simulation stage, but I think you could adopt mos level shifter (schematic from
Hello everyone, schematic Description I am designing RF phase shifter in ADS at 11-12GHz for a beamformer (rf phase shifting topology). The schematic can be seen in the attached image file. As you can see, it's a combination of a 3-bit distributed phase shifter (The Cgs capacitances of the bottom nmos transistors in (...)
digikey told me the level shifter does not exist between 3.3v and 5v but ebay is selling such a module , can someone give me this chip name/number?
I wish to display the adc values coming from serial port to hyper terminal.I have created a level shifter circuit with sine wave (5 vp-p) and 2.5 v dc as inputs and input the data to the pic 16f877a wat i m getting from the terminal are in the range of 2.5-8.6v,since i gave input below 5.0v ,i got more than tat i expected. i have attached
Hello, I am near to end in my project but stuck at some point. I can not resolve the problem After deciding VHDL is having a hard time shifting indexes of arrays, I decided to change my shifter module. Now it is properly compiling and the RTL schematic seems true, but unfortunately I used a rather non-innovative way to shift the scancodes.
hello all, If I am given a schematic of a circuit say level shifter and told to do a layout on the same.What all I should note in steps like( area req, floorplan)...Can anybody tell the steps req by an engineer while designing a layout for given schematic?
Hai i need a schematic diagram for 90 degree phase shifter to draw in cadence . U can just use a meander transmission line to create a 90 degree phase shifter.
Hi, I want to design a switched filter phase shifter using FET for the switch in 9,4 GHz Band. Does anyone has some idea about it.
Hi, I have been working on switched line phase shifter.There is a circuit shared which is i want to implement. 7468974690 I have no experience implementing pcb of microstrip circuit. Will this circuit work in real, if i set up Do you have any video,tutorial vs to help me implementing circ
Hi, I already made fixed phase shifter but I need to make an (variable) analog phase shifter (0-180) with variable control voltage (0-13V) at 2.45 GHz center frequency using ADS tools. Anyone can give me idea about whole circuit schematic or provide me any made schematic.
Check the TIP#15 level shifter in page 46 (4-16), it uses a comparator Alex
You are asking for a -5v to +5v voltage shifter but the input of that stage is from a variable resistor connected to 10v and gnd so I don't understand where do you expert to get that -5v from? Alex
I am a final yr student doing my project..i wanna know if it is possible to design an rf phase shifter ic using cadence..also where will i get the transistor schematic for the phase shifter?? pls help
Hi. I need a lever shifter schematic by transistor that can interface using PIC to GSM/GPRS Module. My objective is to send AT Commands using PIC16F877A to SIMCOM. I followed this guide but still now working. Help me pls.
Hi Evios, No, you don't need a level shifter. Looking at your schematic, you only need two terminal connections on the input and two on the output. Internally, your circuit "ground" connects to the negative input terminal. All of those "0V" power port symbols then connect to that "ground". The negative "LOAD" terminal conne
hi, i need help in designing phase shift and bias tee circuit. my RF signal have bandwidth of from ~1kHz to 20khz. maximum DC signal around 4V. How can I calculate the value of inductor and capacitors needed for bias tee circuit? where can i find any examples of phase shift schematic? another question is how to calculate DC block capaci

the resonance formulla: Fr=1/(2Π√LC) see drawings : second drawing is equvalent circuit and i must to correct my sentens: "if control voltage is higher than 7.5 volt resonance circuit act as inductor. in the other word inductance effect will be dominant. and if V control is lower t
hi simple code for barrel shifter is given in VHDL primer J. Bhaskar book but it is in VHDL . I think its logic can easily be converted to Verilog code bye
I've spent some time trying to google a sollution to this, but nothing so far. Is there any way to program a pic18f452 by connecting it to a pc only with a level shifter, without using a programmer/aditional uC based hardware? Something similar with ponyprog (pony does not support this pic). Thanks, /pisoiu
