Abstract :
This paper introduces the design of the frequency synthesizer for AT-DMB. 0.18um CMOS process with 1.8V supply voltage is used for the frequency synthesizer and the frequency range is from 110MHz to 522MHz for AT-DMB applications. This frequency synthesizer has good linearity by controlling tail current and load concurrently.
