Timing Driver VCO Frequency Adjustment

The patent implements a voltage-controlled oscillator (VCO) that dynamically adjusts its output frequency based on control voltages generated by the timing driver. The VCO frequency can be varied by changing the control voltage, allowing the system to adapt to different frequency requirements while maintaining a relatively simple overall structure. This dynamic adjustment capability resolves the contradiction by enabling frequency adaptation without requiring complete redesign of the timing driver.

The patent changes the operating parameters of the VCO by varying control voltages to adjust the output frequency. The timing driver generates different control voltage levels that directly affect the VCO frequency, allowing flexible frequency adjustment through parameter changes rather than structural modifications. This approach maintains device simplicity while achieving the required adaptability.

The patent incorporates a memory unit that pre-stores multiple control voltage values corresponding to different desired frequency outputs. When frequency adjustment is needed, the timing driver simply retrieves the appropriate pre-calculated control voltage from memory, eliminating the need for time-consuming redesign and reprocessing. This preliminary preparation of control parameters enables quick frequency adjustment while maintaining high frequency accuracy.

The system performs self-adjustment by using the timing driver to generate control voltages that automatically correct frequency deviations. The VCO responds to these control voltages by adjusting its own output frequency to match the desired value, without requiring external redesign or reprocessing interventions. This self-service mechanism reduces both time and costs associated with frequency correction.

The patent implements a universal VCO structure that can operate at multiple frequency values by responding to different control voltages. Instead of requiring separate VCO circuits for each frequency, a single VCO is designed to be controlled by varying voltage levels, making it multi-functional. The memory unit stores control parameters for multiple frequencies, allowing one component to serve multiple frequency requirements, thus improving adaptability without proportionally increasing device size.

The patent embeds the control voltage generation and storage functions within the existing timing driver structure. The memory unit storing control voltages is integrated into the timing driver, and the VCO is controlled by signals generated within the same driver circuit. This nested arrangement allows multiple frequency capabilities to be achieved through internal integration rather than adding separate external components, minimizing the increase in overall device size.
