Apparatus and Method of Adjusting Analog Parameters for Extended Temperature Operation

摘要

A circuit includes a temperature sensor configured to determine a circuit temperature and includes an analog circuit including one or more controllable circuit elements. The analog circuit includes at least one adjustable parameter. The circuit further includes a controller coupled to the temperature sensor and configured to select a threshold temperature. The controller is configured to control the analog circuit in response to the circuit temperature to selectively adjust at least one adjustable parameter of the analog circuit when the temperature exceeds the selected threshold temperature.

1. A circuit comprises:
a temperature sensor configured to determine a circuit temperature; an analog circuit including one or more controllable circuit elements, the analog circuit having at least one adjustable parameter; and a controller coupled to the temperature sensor and configured to select a threshold temperature, the controller configured to determine a transmit/receive state of a circuit, the controller configured to control the analog circuit in response to the circuit temperature to selectively adjust at least one adjustable parameter of the analog circuit when the circuit temperature exceeds the selected threshold temperature and the circuit is not transmitting or receiving and to delay the adjustment when the circuit is transmitting or receiving.
