Linearity Improvement Analysis for PAs at mm- Wave Frequencies Joe Valliarampath Graduate
... scaling of the SiGe HBT is the reduced breakdown voltage, which is caused by impact ionization. However, this breakdown voltage can be overcome by using a 300 Ω at the base of the transistor, resulting in the breakdown voltage shifting from 1.7V to 4 V [10]. The last stage of the PA was designed fo ...

In some applications, complex filters are not really necessary and simple RC low-pass and high-pass networks (6 dB/octave) can be recommended. The results obtained are excellent because this is th ...

MT-044: Op Amp Open Loop Gain and Open Loop
... Open-loop voltage gain, usually called AVOL (sometimes simply AV), for most voltage feedback (VFB) op amps is quite high. Common values are 100,000 to 1,000,000, and 10 or 100 times these figures for high precision parts. Some fast op amps have appreciably lower open-loop gain, but gains of less tha ...
