Sinusoidal oscillators and waveform generators have numerous applications in electronics,
instrumentation, measurement, communications, control systems, and signal processing …

Two important drawbacks of parallel coupled LC quadrature oscillators (P-QOSC) which
have not heretofore been addressed thoroughly in the literature are obviated simultaneously …

This paper presents the design and analysis of phase-tunable injection-coupled quadrature
oscillator (PT-IC-QO). Like other LC QOs, the mismatches between LC tanks are the main …

In this paper, an analytic approach for the estimation of the phase and amplitude error in
series coupled LC quadrature oscillator (SC‐QO) is proposed. The analysis results show …

In this brief, we present a wide operating range quadrature phase LC oscillator with
seamless tunability. A combination of series-coupling and parallel-coupling between two …

This article presents an accurate quadrature phase-locked loop (PLL) with quadrature
phase mismatch calibration for 32 GS/s analog-to-digital converter (ADC). Due to the …

In this work, a novel circuit structure for second-harmonic multi-phase voltage controlled
oscillator (MVCO) is presented. The proposed MVCO is composed of N (N being an integer …

This paper presents a pulse coupling method, in which two resonators are coupled
periodically by a narrow pulse to reshape the current of coupling transistors. In order to …
