چکیده :

This paper introduces a wide bandwidth integer-N Type-I PLL. By using a novel Delay-line based filter as loop filter, the bandwidth of the proposed PLL is about 5 times greater than the bandwidth of traditional Type-I PLL. The chosen strategy in widening the PLL bandwidth is to replace the RC loop filter with a 2-tap delay-line based filter which provides a desired magnitude and phase response. Operating with a reference frequency of 10MHz, the proposed PLL provides a loop BW of about 5MHz, and a spur level of -50dBc. The presented PLL exhibits an in-band phase noise of -119 dBc/Hz at 1MHz offset. PLL total power consumption is 2.5mW from the nominal supply of 1.8V.
