the 30 mA means AC current? peak or peak-to-peak?
or just peak value of a short pulse? because LNA operates with small-signal, there should not be such a large AC current.
Microelectronics is a kind of engineering.....What the application is should depend on those who pay you, such as your supervisor or your sponser.
Just like a company, what their products are should depend on the market and the consumer. even you have foresights on what they need.
It's ok, but since you connect one terminal of inductor to ground, so it's just a single-ended Q
if you use it as a differential Q or some else
(none of terminal is connected to ground)
the former method may be not correct. you should connect the negative of the port to the 2nd terminal of...
Re: High power amplifier energy consumption in payload or BT
The key questions are:
1. How many power do you want to be sent to antenna?
2. your modulation scheme?
constant envelope modulation(MSK/FSK etc.) or linear modulation(BPSK/QPSK or even OFDM and so on)...
Re: improvement of IMD3
It depends on your process, Bipolar or CMOS?
there are some different points of view between different processes..
But in general, bias is very important, not only the decoupling cap or harmonic impedence, but some DC offset in your bias because of even-order...
Momentum don't 'synthesis', but only take EM simulation if you tell him the geometry......
since inductor depends on your layers and substrates,
you'd better search in the inductor lib of your designkits to shrink your searching area
I have read an interesting market infomation of RF PA technology, in an isscc2004 tutorial. which said that 73% of commerial PA (in mobile) is in GaAs, 20% in LDMOS.
But as we know, in recent years, since SiGe technology is rising up, the PA market may have changed...
