第三部分,我們提出了一個具有頻率校正技術的時脈與資料回復電路,這電路中包含了可除小數的鎖相迴路、三角積分調變器以及資料回復電路。在這架構中,我們利用了三角積分調變器的特性,當輸入資料速率發生偏移時,能使回復時脈作頻率及相位的改變。而此時脈與資料回復電路是以0.18微米的互補式金氧半製程製造,晶片實際面積為 1.4×1.4mm2。
最後,我們提出了一個可應用在被動式光纖網路並具有頻率校正技術的時脈與資料回復電路,相較於傳統技術,此電路不但能快速鎖定,而且能在資料速率出現偏差時進行時脈校正,使輸出資料不會受頻率偏移影響。而此時脈與資料回復電路是以0.18微米的互補式金氧半製程作模擬,晶片面積為 1.4×1.4mm2

This thesis mainly describes a clock and data recovery circuit with a frequency calibration technique. The thesis will be divided into four parts. The first part of the thesis introduces Optical Network, the specification of the passive optical network and some common used clock and data recovery architectures. Moreover, we also introduces some common used phase detectors and frequency detectors in a clock and data recovery circuit.
The second part of this thesis introduces the fundamentals of fractional-N phase lock loop, introducing the phase frequency detector, the charge pump, the loop filter and the voltage control oscillator. It is because we use a LC oscillator as a voltage control oscillator in the architecture, we introduce the design of a LC oscillator. Furthermore, the fundamental of the Δ-Σ modulator will also be introduced.
The third part primarily introduces a clock and data recovery circuit with a frequency calibration technique. A 2.5-Gb/s oversampling clock and data recovery (CDR) circuit with frequency calibration is realized for optical communication. The CDR circuit contains a fractional-N phase-locked loop (PLL), a delta-sigma modulator (DSM) and a data recovery circuit. The recovered clock is adjusted by the DSM for phase and frequency tuning, incorporating with the phase detector, when the incoming data rate changes. The CDR circuit is implemented with TSMC 0.18-um 1P6M CMOS technology. The simulation results show the proposed CDR circuit recovers the incoming data.
In the last part, we achieve a 2.5Gb/s Gigabit Passive Optical Network (GPON) clock and data recovery circuit with a frequency calibration technique. The CDR circuit is simulated in TSMC 0.18 RF CMOS technology. Its recovery clock frequency is 2.5GHz, the total power is 128mW, the recovery data output jitter is about 18ps, and the total area is 1.4×1.4mm2
