Effect of Nonlinear Phase Variation in Optical Millimetre Wave Radio over Fibre Systems

In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...

Millimetre-wave 65nm CMOS Class C Oscillator at 65 GHz

A 65-GHz Class-C LC oscillator designed in 65nm CMOS technology by ST Microelectronics is presented. A three spiral transformer has been used to achieve low phase noise and low power consumption. Post-layout simulations show a phase noise is equal to -88.4 dBc/Hz at 1-MHz offset from the carrier (65.8 GHz). The power consumption is 14 mW with 1.2-V supply voltage. The oscillator is capable to o...
