Abstract

The location and fine adjustment of the center frequency as well as the fine adjustment of power in a resonance loop remain a challenge in the field of voltage-controlled oscillator (VCO) design. Firstly, when the conditions of stable oscillation and the VOC with certain types of tuning bandwidth are met, the appropriate circuit configuration needs to be identified. Specifically, in the circuit topology of the oscillator, the varactor-centered reactance compensation network should be connected to the base of the transistor in order to serve as a tuned network, with the output of the emitter followed. By using simulation analyses, the feedback between the electrodes is then achieved by terminating a section of open-circuit microstrip line to the collector. Moreover, the adjustment and variation of the feedback quantity between the electrodes, as well as the variation and fine adjustments of power and frequency are observed during the simulation process. As a result, several issues related to the location and adjustment of the parameters and center frequency in designing a complicated VCO circuit have been effectively settled.
