description: The given work is devoted to the analysis of voltage-controlled oscillator circuits that provide a low level of phase noise and wide tuning ranges and allowing the concept of Software Defined Radio (SDR) to be implemented in future. The aim of the work is to analyze the voltage-controlled oscillator circuits for use in 5G communication systems. Generators based on the Colpitts scheme are characterized by ease of manufacture (require only one transistor), potentially provide the lowest level of phase noise and are able to operate at low voltages. Oscillators based on cross-coupled transistors forming negative resistance were also considered. This type of circuit is most common in practice, because provides a differential signal, has no problems with starting generation and provides the lowest level of phase noise in CMOS technology. Based on the analysis, it was concluded that it is advisable to use oscillators with cross-coupled transistors with combined approaches to suppress noise from a current source.
