This letter proposed a triple-band divide-by-3 injection locked frequency divider (ILFD) fabricated in a 0.18-μm CMOS process. The circuit has two parallel LC-tank. The triple-band function is controlled by switching variables Vtune and Vsw. With the different values of Vtune and Vsw, varactors will also change capacitance, then change the center frequency… CONTINUE READING
