I want to design 20 GHz Colpitts or LC cross coupled oscillator after designing 4GHz cross coupled oscillator.
what is the criteria to select a suitable transistor for high freq VCO?
It is the ft( transition freq)parametre of the transistor which decides(HBT transistor)!!!!!!!
Or simple take any transistor,apply stability factor criteria to find K.
which resonator circuit (MOS capacitor,accumulated or diode connected,LC,)
is suitable for high frequency VCO;
Please answer and discuss in detail.If possible give references.
Thanks in advance.
