Abstract :
This paper presents the design and performance analysis of a ring oscillator using CMOS 90nm technology. A ring oscillator contains odd number of cascaded inverter in which output is oscillating between high and low level. Inverter with minimum delay is best choice for frequency generation. Delay of inverter can reduce by adding secondary inputs and switching these earlier than the primary inputs. High oscillation frequency corporate narrow bandwidth. In this paper, a method to enhance bandwidth has been introduced. 600MHZ bandwidth can be achieved while oscillation frequency is 11GHz.
