Abstract
- This paper presents a quarter-rate forwarded clock (FC) receiver based on an injection-locked oscillator (ILO) which exploits a phenomenon in which phases of the output clock are shifted by the duty-cycle of an injection clock. Also, this paper describes the principle of this phase shifting phenomenon. To utilize the phase shifting phenomenon, a simple duty-cycle adjuster (DCA) is proposed. By using the DCA, the proposed FC receiver achieves 760 MHz of wide jitter tracking bandwidth (JTB) and 60 MHz JTB variation in spite of clock deskew. The proposed receiver achieves a 12 Gb/s data rate with 0.92 mW/Gb/s in a 1 V 65 nm CMOS process. [ABSTRACT FROM AUTHOR]
