Title: VOLTAGE CONTROLLED LC OSCILLATOR WITH CURRENT FEEDBACK AMPLIFIER
Keywords: voltage controlled oscillator, current-feedback operational amplifier, LC selective systems

Abstract: A voltage controlled LC-oscillator is proposed in the paper, realized by a currentfeedback operational amplifier (CFA) with an additional terminal, used for control of some amplifier parameters. A parallel resonant circuit is connected to this amplifier terminal, consisting of an inductor and two varicaps, their capacitance being controlled by dc voltage. In order to ensure the selfoscillation in the whole range of frequency variation, an oscillator design approach is developed, based on simulation testing results. An example is given for the designed according to the developed methodol
