This paper presents the design of a wide band two-stage CMOS voltage-controlled ring oscillator based on the Maneatis cell. The VCO is designed for a frequency synthesizer module that generates local oscillation (LO) frequencies over a large bandwidth, targeting a multi-band acquisition system. The goal is a wide operating frequency tuning range of 400MHz -(More)
This paper presents a two-stage CMOS differential voltage-controlled ring oscillator (VCO). The VCO is intended to operate as a frequency synthesizer in a PLL to generate local oscillator frequency (LO) for an acquisition system, providing in-phase/Q-phase outputs. This work proposes a differential VCO design that has a wide operating frequency tuning range(More)
