Litar pemulihan jam ialah komponen utama dalam sistem penghantaran pemultipleksan pembahagian masa elektrik (ETDM) berkelajuan tinggi. Dalam kes pengekstrakan jam daripada isyarat bukan-kembali-ke-sifar (NRZ), pembezaan dan pembetulan gelombang penuh adalah amat diperlukan. Litar OR/NOR Eksklusif (XOR) digunakan secara meluas untuk tujuan ini. Dalam kertas ini, kami menerangkan IC XOR yang direka dengan 0. 1-µm panjang get InAlAs/InGaAs/InP HEMTs untuk litar pemulihan jam kelas 40-Gbit/s. IC telah dikonfigurasikan dengan gerbang XOR jenis sel Gilbert simetri dan dua jenis teknik memuncak digunakan untuk mencapai kadar bit yang tinggi. Pengukuran pada wafer menunjukkan bahawa IC beroperasi sepantas 80 Gbit/s dan boleh mengekstrak komponen frekuensi 40-GHz daripada isyarat input NRZ 40-Gbit/s. Untuk mengesahkan kebolehlaksanaan menggunakan IC XOR yang dibungkus dalam litar pemulihan jam, keuntungan penukaran IC, yang dikendalikan sebagai pembeza dan penerus gelombang penuh, telah dinilai. Dengan mengandaikan bahawa input kepada litar pemulihan jam ialah 1 Vhlm isyarat, kuasa keluaran yang agak tinggi iaitu -17 dBm boleh diperolehi dengan pergantungan yang rendah pada panjang aliran bit pseudo-rawak input. Tambahan pula, litar pemulihan jam telah dipasang menggunakan IC XOR yang dibungkus, penapis pandu gelombang dan penguat komersial; ia menawarkan kadar bit sistem praktikal 39. 81312 GHz dengan jitter rms rendah 900 fs.

Abstract: The clock recovery circuit is a key component in high-speed electrical time-division multiplexing (ETDM) transmission systems. In the case of clock extraction from non-return-to-zero (NRZ) signals, differentiation and full-wave rectification are indispensable. Exclusive OR/NOR circuits (XOR) are widely used for this purpose. In this paper, we describe an XOR IC fabricated with 0. 1-µm gate-length InAlAs/InGaAs/InP HEMTs for a 40-Gbit/s class clock recovery circuit. The IC was configured with a symmetrical Gilbert cell type XOR gate and two types of peaking techniques are used to achieve its high bit-rate. On-wafer-measurements indicate that the IC operates as fast as 80 Gbit/s and can extract a 40-GHz frequency component from 40-Gbit/s NRZ input signals. To confirm the feasibility of using the packaged XOR IC in clock recovery circuits, the conversion gain of the IC, which was operated as a differentiater and full-wave rectifier, was evaluated. Assuming that the input to the clock recovery circuit is a 1 Vp-p signal, the relatively high output power of -17 dBm can be obtained with low dependency on the length of the input pseudo-random bit streams. Furthermore, a clock recovery circuit was assembled using the packaged XOR IC, a waveguide filter and a commercial amplifier; it offers the practical system-bit-rate of 39. 81312 GHz with the low rms jitter of 900 fs.
