摘要： A comparison system compares a voltage which is proportional to absolute temperature S.sub.p to one which is equal to the sum of a conventional, uncorrected, bandgap cell voltage VBG and a proportional to absolute temperature voltage CT. The addition of CT to the uncorrected bandgap signal value yields a signal of the form Sp/(VBG+CT), which exhibits improved linearity over a signal of the form Sp/VBG, where VBG includes a Tln(T) term.

摘要： A voltage source includes first and second pn junctions which conduct the outputs of respective current sources to establish respective base-emitter voltages Vbe1 and Vbe2 at respective nodes; Vbe1 and Vbe2 can each be generated with a current I or a current N*I. An amplifier A1 has its non-inverting input connected to the second node and its inverting input connected to the first node through an input capacitor; a feedback capacitor is connected between the inverting input and a third node. Switches are connected between A1's inverting input and A1's output, between the third node and A1's output, and between the third node and a circuit common point. A control circuit operates the switches and current sources during first and second operating phases to selectively produce a temperature independent output voltage or a temperature dependent output voltage.

摘要： Electrical networks are formed to produce an approximation of at least one desired performance characteristic, based on the recognition that fabrication variations introduce slight differences in electronic sub-networks which were intended to be identical. These fabrication differences are turned to an advantage by providing a pool of sub-networks, and then selectively connecting particular combinations of these sub-networks to implement networks that approximate the desired performance characteristics. The sub-networks are of like kind (e.g., resistors) and have a like measure.

摘要： A switched current temperature sensing circuit comprises a BJT arranged to conduct a forced emitter current IE of the form Ifixed+(Ifixed/β), such that the base current is given by Ifixed/β and the collector current is given by Ifixed+(Ifixed/β)−(Ifixed/β)=Ifixed. Base current Ifixed/β is mirrored to the emitter, and a current source provides current Ifixed, which is switched between at least a first value I and a second value N*I such that the BJT's base-emitter voltage has a first value Vbe1 when Ifixed=I and a second value Vbe2 when Ifixed=N*I, such that: ΔVbe12=Vbe1−Vbe2=(nFkT/q)(ln N), where nF is the BJT's emission coefficient, k is Boltzmann's constant, T is absolute temperature, and q is the electron charge.
