Description
Summary:This paper presents a fully differential injection locked frequency divider using coupled dual LC tanks. The proposed injection locked frequency divide-by-2 divider achieves a wide locking range with low injected power levels. The divider, fabricated in 0.18μm SiGe BiCMOS process achieves a locking range of 3.77 GHz with an injected power as low as -16 dBm, a phase noise of -116 dBc/Hz at 10 kHz offset with an input referred phase noise of -109.7 dBc/Hz at 10 kHz offset at 25 GHz, maximum output power of -2.44 dBm, efficiency of 18.5% and the DC power consumption is 4.8 mW.
