Abstract:
A low voltage quadrature phase wideband relaxation oscillator. An ultra-wideband tuning range from Mega to Giga Hz order is also realized by tuning the I/Q coupling factor, zeros and poles. Preferably, a novel synchronous quadrature injection lock is proposed to validate low noise performance.
