An analog feedback circuit can be employed to change the determined collector current to be relatively equivalent to the first and second target collector currents. The analog feedback circuit can include an optional sample and hold component to further reduce power consumption and reduce noise.

The method also includes receiving the control signal at a switching circuit, detecting whether the value of the control signal has changed, and, provided the value has changed, switching a plurality of transistors from a first configuration to a second configuration. The first configuration produces a first current in a first circuit and a second circuit, and the second configuration produces a second current in a first circuit and a second circuit. The ratio of the first current and the second current are the aforementioned known ratio.

摘要： A circuit for temperature sensing receives a differential voltage that corresponds to the voltage across a forward-biased PN junction. The circuit for temperature sensing provides a first current to the PN junction, and subsequently provides a second current. Also, the temperature of the PN junction is determined based on the difference between the differential voltage when the first current is applied and the differential voltage when the second current is applied. Further, the circuit for temperature sensing self-biases half of the differential signal. The other half of the differential signal is level-shifted by an amount that is fixed and predetermined based on the self-biasing to provide a sub-ranging voltage. A sub-ranging analog-to-digital conversion is performed on the differential voltage in which the sub-ranging voltage is subtracted from the differential voltage during the conversion.
