A 1.8V, Sub-mW, Over 100% Locking Range, Divide-by-3 and 7 Complementary-Injection-Locked 4 GHz Frequency Divider Conference Paper uri icon

abstract

  • A low-power wideband divide-by-odd-ratio ring-oscillator-based complementary-injection-locked frequency divider (CILFD) is proposed. The multiple-input complementary-injection scheme widens its locking range over 100% to sufficiently cover the PVT variations. The CILFD consumes dynamic power only with no additional power penalty for larger division ratios. The differential input and output are realized employing auxiliary cross-connected inverters. The CILFDs with division ratios of 3 and 7 are implemented in a 0.18 m CMOS technology. The measurement results show a locking range from 1.4 to 4.4 GHz with an input incident power of -4 dBm. The power consumption while locked at 4.7 GHz is 0.9 mW from a single 1.8-V power supply. 2009 IEEE.
