An efficient extremely low frequency digital sinusoidal oscillator with high resolution and extremely low sensitivity is presented. The proposed oscillator structure can generate frequencies much lower than all structures known in the literature without the need to increase the width of the multiplier coefficient. The proposed oscillator utilizes two low sensitivity complex digital oscillators with two different multiplier coefficients. The simulation results verify the analytical results and demonstrate the performance as measured in terms of total harmonic distortion.
