Abstract
A gyrator includes shunt or feedback nodal capacitors and shunt lossy inductors without shunt load resistors. The effective nodal capacitance is reduced by the introduction of the shunt lossy inductors. The inductors act to discriminate against injected power supply noise, resulting in improved oscillator phase noise. The inductors produces less drop dc voltage than the resistive load, so that larger linear oscillation is obtained with improved oscillator phase noise.
