A 6.5\times7\,\mu m2 0.98-to-1.5 mW Nonself-Oscillation-Mode Frequency Divider-by-2 Achieving a Single-Band Untuned Locking Range of 166.6% (4-44 GHz)

The common self-oscillation-mode (SOM) frequency dividers have a high-Q sensitivity curve limiting the locking range (LR). This letter reports a non-SOM (NSOM) frequency divider-by-2. Fabricated in 65-nm CMOS, it occupies a die area of 6.5 × 7 μm 2 , and measures a single-band untuned LR of 166.6% (...

Zusammenfassung:The common self-oscillation-mode (SOM) frequency dividers have a high-Q sensitivity curve limiting the locking range (LR). This letter reports a non-SOM (NSOM) frequency divider-by-2. Fabricated in 65-nm CMOS, it occupies a die area of 6.5 × 7 μm 2 , and measures a single-band untuned LR of 166.6% (4-44 GHz), over a small input range
