发明名称 Negativen Widerstand verwendender spannungsgesteuerter Oszillator
摘要 A voltage controlled oscillator circuit has been provided that allows for varying the center frequency of oscillation through an applied voltage signal (VF). Further, the center frequency of oscillation can be fine tuned around the center frequency via a modulation signal (SM). The voltage controlled oscillator circuit utilizes a negative resistance technique for oscillation and includes an output amplifier whose output resistance can be adjusted to match the input impedance of another circuit for maximum drive capability. <IMAGE>
