Section 2 describes the technology features and advantages related to the bulk CMOS. Section 3 deals with design strategies for both VCO and frequency divider, while experimental results are reported ...

Engineers deem a VCO (voltage-controlled oscillator) capableof covering one octave as state of theart. This topology allows a 4-to-1 ratioin output frequency. The LC tank alonesets this frequency so ...

The VCO was then specified to be able to run from 9.6 GHz (2.4 GHz x 4) to 11.77 GHz ... Realizing multi-stage amplification with all stages built on an LC resonance is very problematic in CMOS due ...

The researchers first generated a voltage-controlled CMOS oscillator, or CMOS VCO, operating at a fundamental frequency of 81GHz with phase-shifted outputs at 0, 90, 180 and 270 degrees, respectively.

Abstract: “This paper presents a 40 GHz voltage-controlled oscillator (VCO) and frequency divider chain fabricated in STMicroelectronics 28 nm ultrathin body and box (UTBB) fully depleted ...
