Abstract

A triple-band divide-by-2 LC injection-locked frequency divider (ILFD) was implemented in the TSMC 0.18 μm 1P6M CMOS process, and it uses a cross-coupled nMOS pair and two shunt 4th order LC resonators to form a 6th order resonator with three resonant frequencies. Measured data has shown that the ILFD has three locking ranges at fixed bias condition or by varactor bias switching.
