Design of Beyond Millimeter Wave Oscillator in 22nm Bulk CMOS technology

2019 International Journal of Engineering and Advanced Technology  
This paper presents the design of an LC oscillator using inductive feedback technique in bulk CMOS 22 nm technology using predictive technology models. The core oscillator is based on the popular Cherry Hooper amplifier topology. The development of the oscillator circuit from the standard Cherry Hooper topology is discussed in this paper with detailed analysis. The inductors are modelled by considering the various effects in this frequency range. The broadband technique used in the CH topology

By employing MOS varactors the designed oscillator was converted into a voltage-controlled oscillator also. The fundamental mode of the oscillator is around 372 GHz with a phase noise measured around -70 dBc/ Hz at 10 MHz offset. The VCO has a tuning range of about 490 MHz when the voltage is varied from 0.3 to 0.8 V. The oscillator circuit consumes power of 3.75 mW from a power supply of 0.8 V
