| Popis: | This letter presents a wide locking range divide-by-4 LC injection-locked frequency divider (ILFD) implemented in the TSMC 0.18- $\mu \text{m}$ 1P6M CMOS process. The single-stage divide-by-4 ILFD uses harmonic mixer and overlapped locking ranges to emulate a wide locking range. At the drain–source bias of 0.8 V, the ILFD-core power consumption is 7.09 mW. At the incident power of 0 dBm, the maximum locking range of the divide-by-4 ILFD is 6 GHz (37.5%) from 13 to 19 GHz. The ILFD comprises a capacitive cross-coupled nMOS pair and two shunt fourth-order RLC resonators. The die area is $1.008\times1.182$ mm $^{{{2}}}$ . |
