Welcome to our site! EDAboard.com is an international Electronics Discussion Forum focused on EDA software, circuits, schematics, books, theory, papers, asic, pld, 8051, DSP, Network, RF, Analog Design, PCB, Service Manuals... and a whole lot more! To participate you need to register. Registration is free. Click here to register now.
After you have designed some circuits, you will found the "signal and system" and DSP is very important!
If you have no knowlege of it, you can not begin you design.
sigle-ended recievers?
SSN is simultaneous switch noise. This is a challenging of high speed IO. when many signal of IO switch simulaneous, they will drop a lot of current of IO. there will be great bounce at the supply and gnd.
All the single-ended signal is sensitive to commmon mode noise.
About bandgap circuit
In general, bangap will generate a voltage of 1.2V.
You can apply the 1.2 to a resistor to generte a current and then use current mirror to enlarger the current by 2.1/1.2. Let the current pass the same resistor you will get 2.1v voltage.
IF you use a cystal under 30Mhz , the cystal will work at fundamental mode. IF the frequence larger than 30Mhz, the crystal have to work at overtone model. the circuits for cystal of fundametntal mode and overtone mode is difference!
i2c glitch filter
If you built a switch delay filter to suppress 50ns of signal, you need another clock signal. I agree with rajesh13, his resolution is simpler & effective.
i2c pulse filter
what the 50ns means?
does it need to combined with the VHYS of the following schmitt trigger ?
Then the signals witch pulse width is smaller than 50ns can not pass the schmitt trigger.
If so, why can I not use a signal witch is the Xor of the input signal and 50ns delay input...
