Abstract

This paper proposes Progressive Mixing Injection Locked Frequency Divider (PMILFD) technique that enhances the locking range for higher division ratios. As this technique uses lower and much stronger harmonics in the mixing process, it results in a stronger injection effect and a much wider locking range. Two 20GHz PMILFDs were designed based on this approach to divide by 4 and 8 using a 65nm CMOS process. The former achieves a 7.9GHz(31.4%) locking range and the later achieves a 3.4GHz(15.5%) while consuming 3.9mW and 7.1mW, respectively.
