Title:
VOLTAGE WAVEFORM SHAPING OSCILLATOR
Document Type and Number:
WIPO Patent Application WO/2018/023367
Kind Code:
A1
Abstract:
A voltage waveform shaping oscillator, comprising a signal source (101) and a coupling transformer (102), an output end of the signal source (101) being connected to an input end of the coupling transformer (102), and an input end of the signal source (101) being connected to an output end of the coupling transformer (102); the signal source (101) is used for receiving, by means of the input end of the signal source (101), a quasi-square wave signal outputted from the output end of the coupling transformer (102), generating an original signal on the basis of the quasi-square wave signal, and sending the original signal to the input end of the coupling transformer (102) by means of the output end of the signal source (101), the original signal being an oscillation signal, and the output end of the signal source (101) being an output end of the oscillator and being used for outputting an original signal; the coupling transformer (102) is used for receiving the original signal by means of the input end of the coupling transformer (102), performing wave filtering processing of the original signal to obtain a quasi-square wave signal, and sending the quasi-square wave signal to the input end of the signal source (101) by means of the output end of the coupling transformer (102). The present invention is used for reducing the phase noise of the oscillator.
