A 1.2 GHz programmable DLL-based frequency multiplier for wireless applications.

A 1.2 GHz programmable DLL-based frequency multiplier for wireless applications.

A CMOS local oscillator using a programmable delayed-lock loop based frequency multiplier is present in this paper. The maximum measured output frequency is 1.2 GHz. The frequency of the output clock is 8× to 10× of an input reference clock between 100 to 150 MHz at simulation. No LC-tank is used in...
