METHODS AND SYSTEMS FOR REDUCING A FREQUENCY DRIFT IN A VOLTAGE CONTROLLED OSCILLATOR (VCO) - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240322756 titled 'METHODS AND SYSTEMS FOR REDUCING A FREQUENCY DRIFT IN A VOLTAGE CONTROLLED OSCILLATOR (VCO)
The abstract describes a circuit designed to reduce temperature-induced frequency drift in a voltage to current (V2I) converter-based voltage-controlled oscillator (VCO) for a wide band phase-locked loop (PLL).
- The circuit includes a V2I resistor node, a VCO, and a current-controlled oscillator (CCO).
- It provides a fixed offset current to the V2I resistor node to make the V2I output current inversely proportional to absolute temperature (CTAT).
- The V2I output current is mirrored to the CCO to reduce temperature-induced frequency drift in the lower frequency band of the VCO.
Potential Applications: - Telecommunications - Radar systems - Wireless communication devices
Problems Solved: - Reducing temperature-induced frequency drift in VCOs - Improving the stability and accuracy of PLLs
Benefits: - Enhanced performance in varying temperature conditions - Increased reliability and precision in frequency control
Commercial Applications: Title: Temperature-Compensated VCO Circuit for Improved Frequency Stability This technology can be utilized in various industries such as telecommunications, radar systems, and wireless communication devices to enhance frequency stability and performance.
Questions about the technology: 1. How does the circuit in the V2I converter help reduce temperature-induced frequency drift?
The circuit provides a fixed offset current to the V2I resistor node, making the V2I output current inversely proportional to absolute temperature, which helps stabilize the frequency in varying temperature conditions.
2. What are the key components of the circuit that contribute to reducing frequency drift?
The V2I resistor node, VCO, and CCO work together to provide a stable output current that minimizes temperature-induced frequency variations.
Original Abstract Submitted
a circuit for reducing a temperature-induced frequency drift in a voltage to current (v2i) converter based voltage-controlled oscillator (vco) for at least one wide band phase-locked loop (pll), the circuit includes a v2i resistor node of the v2i converter, the v2i resistor node being at one end of a resistor, the vco, and a current controlled oscillator (cco), and the circuit is configured to provide a fixed offset current to the v2i resistor node to cause at least one v2i output current to have a value conversely proportional to absolute temperature (ctat), the at least one v2i output current being output by the v2i converter, and mirror the at least one v2i output current to the cco to reduce the temperature-induced frequency drift at a lower frequency band of the vco.
