Summary: 
A novel comparator-based switched-capacitor voltage-to-frequency converter is presented. By using the op-amp as the comparator, it can be operated over wide frequency range. Conversion sensitivity is also insensitive to capacitance ratio and parasitic capacitances between each node and ground.
