Owing to the nanoscale CMOS technology, mm-wave circuits have been recently attracting a lot of attention for communication, sensing and imaging systems. Several mm-wave components with operation frequencies around or more than 100GHz have been reported [1-7]. The frequency divider is one of the key building blocks in wireless transceivers. Several W-Band (75 to 110GHz) and D-Band (90 to 140GHz) ILFDs [3-6] and static dividers [7] have been presented. In this work, a 128.24-to-137.00GHz CMOS ILFD with splitinjection and split-cross-coupled pair is presented for D-Band applications. Figure 16.5.1 shows a distributed-LC ILFD [5]. Neglecting the injection MOSFET, Minj, the input impedance is calculated as =LQ = V //& + V ( / + / ) V //&& + V  ( /& + /& + /& ) +    (1) where the capacitors, C1 and C2, indicate the total equivalent parasitic capacitance at the nodes C and D, and A and B (Fig. 16.5.1). Then, the
