“…Oscillator phase noise (PN) is one of the main bottlenecks for the information capacity of communication systems, leading to severe challenges in the design of local oscillators in silicon technologies, especially at very high frequency [ 1 – 5 ]. In particular, the main difficulties are to achieve a high quality factor LC tank [ 6 – 11 ] and consume reasonable power [ 12 , 13 ].…”

This paper reports comparative analyses of phase noise in Hartley, Colpitts, and common-source cross-coupled differential pair LC oscillator topologies in 28 nm CMOS technology. The impulse sensitivity function is used to carry out both qualitative and quantitative analyses of the phase noise exhibited by each circuit component in each circuit topology with oscillation frequency ranging from 1 to 100 GHz. The comparative analyses show the existence of four distinct frequency regions in which the three oscillator topologies rank unevenly in terms of best phase noise performance, due to the combined effects of device noise and circuit node sensitivity.

“…Phase Noise (PN) of integrated oscillators is the main bottleneck regarding the number of users that could use a given bandwidth [1]. This imposes severe requirements for the local oscillators in wireless communication transceivers [2,3] and their implementation on silicon technologies, especially at very high frequency [4].…”

Comparative Phase Noise (PN) analysis of Hartley, Colpitts and Cross-coupled LC oscillators at 10 GHz in 28-nm CMOS technology is reported. The results of the PN direct plots in the Cadence-SpectreRF design environment are compared with the results obtained by the Impulse Sensitivity Function (ISF). The steps for deriving accurately the ISF are reported and discussed. The results show a very good agreement in a set of conditions, and confirm that the LC cross-coupled differential oscillator exhibits superior PN performance with respect to Colpitts and Hartley, and also that Colpitts exhibits slightly superior performance with respect to Hartley.

“…ROF has been regarded as a key technique to meet bandwidth requirements for delivering multi-Gb/s data and video services to large number of users because it shows many advantages such as low-cost, decreasing power consumption, large bandwidth, high-transmission performance and so on [10]. Moreover, in order to improve the transmission rate, orthogonal frequency division multiplexing (OFDM) has attracted a lot of attention recently [11][12][13]. Among various digital signal processing methods, the OFDM is promising for its intrinsic advantages such as flexibility of spectral division, high spectral efficiency and the outstanding tolerance against chromatic dispersion and polarisation mode dispersion.…”

A novel full duplex cost-effective hybrid radio-over-fibre passive-optical-network based on external modulation of a distributed feedback laser diode and dual-drive Mach -Zehnder modulator with multi-wavelength output characteristic is proposed and experimentally demonstrated. Baseband non-return-to-zero (BB-NRZ) signals, radio-frequency NRZ (RF-NRZ) signals, as well as RF orthogonal frequency division multiplexing (RF-OFDM) signals are successfully transmitted simultaneously. After transmission over 50 km of a single-mode fibre, low-bit-error rate and clear eye diagram are achieved for BB-NRZ and RF-NRZ transmission system. The power penalties for BB-NRZ, RF-NRZ and RF-OFDM downstream signals are less than 1 dB. The frequency of local oscillator signal is reduced because of frequency quadrupling scheme. Compared with recent schemes, the cost of the proposed system is largely reduced.
