Re: Cgs Cgd Which one is more important for Class-AB pa desi
Cgs is more important. Cgs normally is between input port G and ground, but Cgd is between input port G and output port D and can be effectively divided to two parts C1 and C2 by Miller Effect. C1 and C2 are between G/Ground and...
Re: pHEMT Gate Biasing
Do you known the concept of Bias Tee?
You should insure that DC bias port is very-high impedance (open) for RF frequency.
The high resistance series resistor you used paved the way.
Hi All:
I'm planning to design a 850MHz differential PA using 0.18um CMOS technology for my course project. The design specification is P-1dB=20dBm, G>8dB.
Would you please give some advices or papers? Some about the design procedures or circuit topologies...
Thank you very much!
