| 20080259989 | Systems and Methods for Temperature Measurement Using N-Factor Coefficient Correction - Various systems and methods for temperature measurement are disclosed. For example, some embodiments of the present invention provide temperature measurement systems. Such temperature measurement systems include a variable current source and a diode connected transistor. The variable current source is capable of applying two or more distinct currents to the diode connected transistor. The currents result in a different base-emitter voltage on the diode connected transistor. The systems further include an n-factor coefficient register and an analog to digital converter. The analog to digital converter is operable to receive two of the base-emitter voltages created by applying the different currents, and to provide a digital output based at least in part on a value stored in the n-factor coefficient register and the two base-emitter voltages. | 10-23-2008 |
| 20080259997 | Systems and Methods for PWM Clocking in a Temperature Measurement Circuit - Various systems and methods for pulse width modulated clocking in a temperature measurement are disclosed. For example, some embodiments of the present invention provide temperature measurement systems with a variable current source, a transistor, and a pulse width modulation circuit. The variable current source is operable to provide a first current and a second current that are applied to the transistor. A first base-emitter voltage occurs on the transistor when the first current is applied, and a second base-emitter voltage occurs on the transistor when the second current is applied. The first base emitter voltage is associated with a first sample period, and a second base-emitter voltage is associated with a second sample period. The pulse width modulation circuit provides a pulse width modulated clock including a combination of the aforementioned first period and second period. | 10-23-2008 |
