a single CMOS inverter with a cap to ground on input and output and a 
crystal between input and output and a large resistor between input and 
output is a very common oscillator in microcontrollers.

I've used ECL buffers as the gain element in oscillators before, but 
most that I've done were with individual transistors with the exception 
of a low distortion audio oscillator which used an op-amp for the gain 
element.
