Such temperature measurement systems include a variable current source and a diode connected transistor.

摘要： An identification address of a sensor interface device is configured in response to the order of connection of first (DXP1) and second (DXN1) package pins to electrodes of a sensor (Q0). A sensor signal processing circuit (23) has first and second inputs coupled through the first and second pins to the sensor for converting a parameter sensed by the sensor to a different representation. A current is forced through the first pin to produce either a high or low voltage on the first pin depending on the order of connection of the first and second pins to the electrodes of the sensor. A voltage on the first pin is compared with a reference voltage to produce a comparison signal which is mapped to produce the identification address.

摘要： A reconfigurable circuit (10) includes an integrator (30) having switches (SW1-6) for selectively coupling input capacitors (C0,1,2,3,6,7) and integrating capacitors (C4,5) to terminals of the integrator (30) for operation of a hybrid delta-sigma/SAR ADC (400) so as to create a reference voltage value (Vref) equal to the sum of a first voltage (ΔVbe) and a second voltage (Vbe). A first integration is performed to reduce the integrator output voltage swing. A residue (Vresidue) of the integrator is multiplied by 2. Then the second voltage (Vbe) is integrated in a first direction if a comparator (22) coupled to the integrator changes state or in an opposite direction if the comparator does not change state. The first voltage (ΔVbe) is integrated in a direction that causes the integrator output voltage (Vout) to equal either 2×Vresidue−Vref or 2×Vresidue+Vref.
