Oscilator reguliranog napona (VCO) s trostepenim nesimetričnim prstenastim oscilatorom (SERO) postavljen je za rad od 2,4 GHz do 5,42 GHz u bežičnim komunikacijskim sustavima uskog frekventnog područja kao što su Wi-Fi, Bluetooth i Zigbee. Primijenjeno je jednostrano vrijeme kašnjenja ćelije da bi se predloženi VCO postavio u standardni 0,18-µm CMOS postupak. Taj VCO troši samo 664,51 µW snage. Da bi se postiglo široko frekventno područje od 55,72 %, reguliranje napona varira od 0,7 V do 1,8 V. Rezultat fazne buke nakon simulacije je −107,59 dBc/Hz kod 1 MHz pomaka od srednje frekvencije od 4,3 GHz. Strujni krug je projektiran i simuliran korištenjem Mentor Graphics okruženja. ; A 3-stage single-ended ring oscillator (SERO) based voltage controlled oscillator (VCO) has been proposed to operate from 2,4 GHz to 5,42 GHz for short range wireless communication systems, such as Wi-Fi, Bluetooth and Zigbee. Single-ended delay cell has been adopted to form the proposed VCO in standard 0,18-µm CMOS process. This VCO consumes only 664,51 µW of power. To achieve wide tune range of 55,72 %, control voltages are varied from 0,7 V to 1,8 V. The post-layout simulation result of phase noise is −107,59 dBc/Hz at 1 MHz offset from the centre frequency of 4,3 GHz. The circuit is designed and simulated using Mentor Graphics environment.
