A quadrature based voltage controlled oscillator (VCO) local oscillator (LO) system is disclosed. The system includes a phase detector, a quadrature phase VCO, a quadrature control path, an in-phase control path, and an in-phase VCO. The phase detector is configured to compare and generate phase error between a reference clock and an in-phase VCO output. The quadrature control path configured to generate a quadrature control voltage based on a quadrature VCO output and the in-phase VCO output. The quadrature phase VCO configured to generate the quadrature VCO output based on the quadrature control voltage and the generated phase error. The in-phase control path configured to generate an in-phase control voltage based on the quadrature VCO output and the in-phase VCO output. The in-phase VCO is configured to generate the in-phase VCO output based on the in-phase control voltage and the generated phase error. An all digital dual mode phase locked/phase tracking loop LO generate system is also disclosed.

Quadrature local oscillator signal generation systems and methods

Embodiments herein may relate to an optoelectronic receiver that includes a photonic integrated circuit (PIC) coupled with a light source. Respective PIC sections of the PIC may include a photodiode and a junction capacitor. The optoelectronic receiver may further include an electronic integrated circuit (EIC) coupled with the PIC. Respective EIC sections of the EIC may be communicatively coupled to respective ones of the PIC sections. Other embodiments may be described and/or claimed.
