Current-mode sinusoidal quadrature oscillator with independent control of oscillation frequency and condition using CDTAs

open access: yes, 2010
363-366A current–tunable current-mode sinusoidal quadrature oscillator, constructed from only three current differencing transconductance amplifiers (CDTAs) and two grounded capacitors with the absence of the passive resistors, is presented and ...

DCIS 2006 Analysis and Design of Quadrature LC Oscillators

open access: yes, 2008
– Single LC oscillators are known for their good phase noise performance. In this paper we analyse the effect of cross-coupling two LC oscillators in order to provide quadrature outputs, which are mandatory in modern transceiver architectures. We present
