CONTINUATION ANALYSIS OF A PHASE/QUADRATURE ELECTRONIC OSCILLATOR

Journal of Circuits, Systems and Computers, 2010
An RF phase-quadrature oscillator is analyzed. The designer "ensured" the phase-quadrature working condition through a suitable cross-coupled electrical connection between the two parts composing the complete oscillator. Through a detailed analysis of the dynamics of this oscillator, we show that device mismatch can lead to an unexpected stable ...

On the quadrature accuracy of in-phase coupled quadrature LC oscillator

Integration, 2020
Abstract In this article, closed-form equations are proposed for phase and amplitude errors of an in-phase coupled quadrature LC oscillator. First of all, the injected current from coupling network to switching one is analytically calculated in a novel approach.

Quadrature Oscillator Realization Based on DDCC+

2020 28th Signal Processing and Communications Applications Conference (SIU), 2020
In this work, a new DDCC+ based mixed-mode quadrature oscillator (QO) topology is proposed. The proposed QO circuit consists of three DDCC+s, two floating resistors, two grounded resistors and two grounded capacitors. When compared to the other DDCC based QOs in literature, the proposed DDCC+ based QO circuit in this work possesses the advantages of ...

Evolution of Oscillation in a Quadrature Oscillator

2011 24th Internatioal Conference on VLSI Design, 2011
The growth of oscillation in a quadrature oscillator that employs phase shifters in the coupling-path between a pair of LC-loaded negative resistance cores, is analyzed. Such an oscillator is known to have two stable modes of oscillation. Under a noise-initiated startup from an unstable initial condition, quasiharmonic assumption and the Method of ...

Analysis and design of an optimally coupled 5-GHz quadrature LC oscillator

IEEE Journal of Solid-State Circuits, 2002
A 5-GHz quadrature LC oscillator has been realized, in which the two LC stages are coupled with phase shifters. Analysis on the behavioral level shows that an N-stage LC oscillator is optimally coupled when each stage is connected with phase shifters ...

A Magnetically Tuned Quadrature Oscillator

IEEE Journal of Solid-State Circuits, 2007
Continuous frequency tuning by control of the magnetic field of a transformer - capacitor tank, in a selective oscillator, is explored in this work. A quadrature generator is built connecting two identical transformer - capacitor oscillator cells in a feedback loop.
