- Abstract
- A 17.8-34.8 GHz (64.6%) locking range current-reuse injection-locked frequency multiplier (CR-ILFM) with dual injection technique is presented in this paper. A dual injection technique is applied to generate differential signal and increase the power of the second-order harmonic component. The CR core is proposed to reduce the power consumption and compatibility with NMOS and PMOS injectors. The inductor-capacitor (LC) tank of the proposed CR-ILFM is designed with a fourth-order resonator using a transformer with distributed inductor to extend the locking range. The self-oscillated frequency of the proposed CR-ILFM is 23.82 GHz. The output frequency locking range is 17.8-34.8 GHz (64.6%) at a 0-dBm injection power without any additional control including supply voltage, varactor, and capacitor bank. The power consumption of the proposed CR-ILFM is 7.48 mW from a 1-V supply voltage and the die size is 0.75 mm x 0.45 mm. The CR-ILFM is implemented in a 65-nm CMOS technology.
