Abstract :
This paper discusses the design and development of a multi-vibrator oscillator, the design and development of an integrated circuit (IC) Colpitts oscillator and performance comparison of the two oscillators regarding frequency lock-in behavior. Experiments were conducted to determine frequencies at which lock-in is most likely to occur and recommendations are made to prevent locking of oscillators that are used in RFID telemetry systems.
