Abstract
In a voltage-controlled LC oscillator, a series LC resonance circuit is connected between two transistor amplifying stages which provide low impedance input and output circuits for the LC circuit. The collector of the first transistor stage is connected through a coil to the operating voltage. The emitter of the second transistor stage is connected to the reference voltage through a coil. This will result in narrowband transistor stages and significant advantages in the power consumption and other characteristics of the oscillator.
