Abstract:This paper presents the design of five-stage current controlled inductor-less ring oscillator that were simulated in Silterra 0.18um CMOS Technology with oscillation frequencies up to 5.99 GHz. The design uses cross coupled MOS devices along with active inductor (thus inductorless) and controlled by current source to aid in switching speed and to improve the noise parameters. The simulations show that the five-stage oscillator achieves frequency in the range of 3.78GHz to 5.99GHz. The simulated phase noise of … Show more
