摘要: This study implemented an injection-locked frequency divider (ILFD) on Ka-band millimeter-wave communication systems in 0.5μm enhancement/depletion-mode (E/D-mode) GaAs PHEMT technology. The ILFD presents a low-power design based on the differential-injection circuit topology without using any injectors. Compared with the conventional single-injection ILFD circuits, the proposed ILFD exhibits output power flatness and wide locking range characteristics with a power consumption of 0.9mW under a 0.4V supply. The self-oscillation frequency was chosen to be 20GHz for divided-by-2 operation. The measured locking range is approximately 11.5GHz ranging from 32.5GHz to 44GHz when the injection power level is 5dBm. The locking range exhibiting a 3dB power roll-off characteristic at output is 10.5GHz ranging from 33GHz to 42.5GHz. 出版者: Elsevier Ltd 出版日期: 2013-12 出處: Microelectronics, 2013-12, Vol.44 (12), p.1285-1289 版權: 2013 Elsevier Ltd 識別號: ISSN: 1879-2391 識別號: ISSN: 0026-2692 識別號: DOI: 10.1016/j.mejo.2013.08.017
