Millimetre-wave 65nm CMOS Class C Oscillator at 65 GHz
نویسندگان
چکیده
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 operate even with supply voltages as low as 0.5V, still maintaining good phase noise performance of -84.5 dBc/Hz @ 1-MHz from the carrier (64.1GHz), and a very low power consumption of 1.9 mW only.

متن کاملEffect 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...
