摘要：
Contrary to what happens with LC oscillators, the increase of coupling in cross-coupled relaxation RC-oscillators leads to a lower quadrature error and lower phase-noise. We present a 2.4 GHz CMOS quadrature relaxation oscillator, and show the measurements confirming this property. Increasing the coupling block gain, the oscillator phase-noise is reduced from -97 dBc/Hz to -104 dBcfHz @ 1 MHz. The quadrature error is reduced from 4.3 degrees to 0.8 degrees. These results show that RC quadrature oscillators may be a practical alternative for RF transceiver applications.
