US Patent 7556206 Temperature compensated clock delay closed loop circuit

Embodiments of the present invention provide a temperature compensating circuit. The circuit generally includes a clock element operable to provide an adjustable clock signal, a buffer element coupled with an analog-to-digital converter and operable to receive the adjustable clock signal, a temperature sensor operable to sense a temperature, and a logic element coupled with the clock element and the temperature sensor. The logic element is operable to acquire the temperature from the temperature sensor and adjust the clock signal based upon the acquired ambient temperature. Such a configuration compensates for temperature variations and reduces system complexity and required component space, thereby providing a compact and efficient design.
