PURPOSE: An N-th order arbitrary-phase-shift wave oscillating structure and an analytical synthesis method thereof are provided to obtain very accurate phase shifts by executing a compensation scheme related to phase shifts. CONSTITUTION: An N-th order arbitrary-phase-shift sine wave oscillating structure comprises a first ground capacitor, a second ground capacitor, a first operational transconductance amplifier, and a second operational transconductance amplifier. The first non-inverting output of the second operational transconductance amplifier is connected to the first inputs of the first and the second operational transconductance amplifiers and the output of the first operational transconductance amplifier. The first inverting output of the second operational transconductance amplifier is connected to the second input of the first operational transconductance amplifier and the second ground capacitor. The second input of the second operational transconductance amplifier is connected to the ground.
