Abstract
In Self Oscillating systems, locking of the oscillators can take place for injected signals close in frequency to nth harmonics of the free-running frequency. In this paper, we present a simple design for digital phase shift control by using a harmonically injection locked oscillator (ILO) of 35MHz frequency. Phase shifters at high frequencies are essential in many communication system applications such as frequency synthesis, quadrature signal generation and phase locked loops (PLLs).
Highlights
In Self Oscillating systems, oscillators locking can occur when signals close in frequency to nth harmonics of the freerunning frequency are injected [1,2,3,4,5]
The superharmonic injection locked oscillator is designed and implemented using a Colpitts oscillator which has a free-running frequency of 35MHz. This frequency is used as the intermediate frequency (IF) in low capacity FM-FDM and PSK-PCM communication systems
By injecting a signal harmonically related to the oscillator free-running frequency, a dual function of locking and phase shifting may be achieved
