I thank you for very concise input, it shows that old ttl bipolar technology circuits are somewhat less efficient than the newer HCMOS types, this is one good reason why cpu manufactures use MOS and not bipolar but not the only reason.
If I have a Colpitts oscillator, then it's frequency determining components, i.e., capacitance and inductance (L/C tank circuit), then to make high frequency oscillator I make C/L very small, if I want low a frequency oscillator I make (L/C) components very large. Remember, pure reactive components do not consume power/ energy, but they do store electrical energy.
Think of a 600Watt microwave cooker, we will make the assumption that it has 100% conversion efficiency from 600Watts 50Hz to 600watts to many GHz frequency, i.e., very short wavelenths. Of course microwave cookers are not 100% efficient, I know but I try to keep things simple.How can 50Hz 600watts change to many GHz frequency, whilst taking the same power from mains, yes, that doesn't make sense does it??
But it does make sense if we except Mr OHM's law, and use the well known r.m.s. equation which is independent of low or high frequency. Here's a link which might help...
