Abstract: This letter proposes a Virtual Oscillator Phase-Locked Loop (VO-PLL) that integrates an Andronov-Hopf oscillator to improve synchronization in distorted grid. VO-PLL replaces the ...

The autotuner is realized as a PLL coupled to the crystal-oscillator frequency, whereby the VCO in the autotuner is a replica ... Figure 3 shows the basic gm-cell. It consists of inverter-stages for ...
