In a colpitts oscillator, such as this one from wps.prenhall.com:
there is no collector resistor. Instead there's a collector inductor, which is a short at DC. The inductor blocks the oscillating signal from the supply line, but what about the CE amplifier you see here with respect to DC? Why is the transistor not being overpowered by a very small resistance connection from collector to Vcc? My guess is that the RFC provides little, but enough resistance, as a low Q inductor would have at least some resistance, but that's not all that fulfilling. Really appreciate any help! Thanks
