| titleOfInvention | Active egg oscillator drive |
| abstract | 1. TECHNICAL FIELD OF THE INVENTIONn n n The present invention relates to a Yttrium-Iron-Garnet (YIG) oscillator drive device.n n n 2. The problem that the invention is trying to solven n n SUMMARY OF THE INVENTION The present invention provides an egg oscillator control device for improving stability of an output frequency of an egg oscillator and reducing a frequency setting speed by actively controlling a main coil of an egg oscillator using an output voltage of a phase locked loop (PLL). There is this.n n n 3. Summary of Solution to Inventionn n n The present invention provides an active egg oscillator driving apparatus comprising: control means for generating output digital information corresponding to an output frequency to control a phase locked loop; Bit UP and bit DOWN digital signal generating means for generating a comparison output by comparing the connection line for inputting the voltage from the control means with the comparison key and the received voltage with a high reference voltage and a low reference voltage; Digital control means for raising and lowering a digital bit by receiving a signal generated from the UP and DOWN digital signal generating means; Digital / analog conversion means (DAC) for converting the digital bits received from the digital control means into analog signals; Voltage / current conversion means for converting the voltage received from the digital / analog conversion means into a current; And an egg oscillator for generating an output frequency using a magnetic field generated by the output current of the voltage / current converting means.n n n 4. Important uses of the inventionn n n The present invention is used to drive an egg oscillator.n n n n YIG Oscillator, Main Coil, FM Coil, FM Coil, Frequency Synthesizer, Reference Voltage Generator, Driving Circuit |
