Hi All,
I'm simulating a simple single-ended Class E power amplifier with certain GaN HEMT under 2GHz or higher. Its output power is around 10W.
The strange thing is that the supply voltage (drain bias voltage) can influence the optimum efficiency dramatically...
For example, when the...
I'm working on a PCB implemented first order CT Sigma Delta Modulator with very slow input signal <10Hz; 200KHz sampling frequency.
I have completed my board and got some results. Good news is that the board can work, but the SNR performance is only 45 dB...and my expected value is 100 dB...
I...
I want to pick some switch ICs for my PCB board. I have determined the IC type, which is ADG719BRTZ-500RL7 or ADG719BRTZ-REEL7, both are ADI products.
Now I'm confused by the suffix "500RL7" and "REEL7". I cannot find any information about these on datasheet. Thus, does anyone know something...
I'm designing a simple first-order sigma-delta modulator with RC
integrator.
Now I want to define the minimume and maximum sampling frequency of
this modulator. Of course, minimume fs can be found by investigating
the integrator output voltage --- if the fs is too low, the output
voltage will...
a problem when browsing the tea5777's datasheet
It says that "the IF counter result is a 1-bit output and in-window yes or no and
available via bus control...In both AM and FM modes, two IF window settings
can be chosen by bit IFW".
Then what`s meaning of "IF window" and "in-window"?
Thx for...

It shows "could not read part information" when I download new parts from ICA. I looked through the FAQ on "http://www.orcadpcb.com/kb_articles/cis02677.asp". But it`s all about local part database. So Has somebody solutions? THX...
