A simple linear impedance analysis is presented to predict the amplitude and distortion of oscillation. The accuracy of this approach is examined by comparing calculated, simulated and measured results. Transconductance tuning keeps the startup condition satisfied within the frequency range from 2 to 11 MHz.0.5 mum2 to 11 MHzCMOS digital processOTA-C integratorsTHDdifferential oscillatorlinear impedance analysisoscillation amplitudeoscillation distortionstartup conditiontransconductance tuningtwo-stage high swing fully integrated tunable quadrature sine oscillatortwo-stage operational transconductance amplifier-capacitor sine oscillator circuitCMOS analogue integrated circuitscircuit tuningharmonic distortionoscillatorstext::journal::journal article::research article
