The design of oscillator is need of today's circuits; The PLL uses this oscillator for different devices. The use of ring oscillator gives benefit in term of size and wide tuning range. The authors can use LC oscillators for low noise, but on the cost of area needed. To improve performance of circuit they uses differential delay cell. This paper is based on review of different VCO. The ring oscillator with differential stages is the one which fulfill the parameter which they are analyzed.
