Abstract: A circuit for generating a bandgap voltage includes a circuit module for generation of a base-emitter voltage difference formed by a pair of PNP bipolar substrate transistors which identify a first current path and a second current path. A first current mirror of an n type is connected between the first and second branches and is further connected via a resistance for adjustment of the bandgap voltage to the second bipolar transistor. A second current mirror of a p type is connected between the first and second branches, and connected so that the current mirrors repeat current of each other. In operation to generate the bandgap voltage, current flows from the supply voltage to ground only through said the first and second bipolar substrate transistors.

Abstract: A circuit includes a first input terminal, a second input terminal, a third input terminal and an output terminal. A first summation node adds signals at the first and third input terminals. A second summation node subtracts signals at the second and third input terminals. A selector selects between the added signals and subtracted signals in response to a selection signal. The output of the selector is integrated to generate an integrated signal. The integrated signal is compared by a comparator to a threshold, the comparator generating an output signal at the output terminal having a first level and a second level. Feedback of the output signal produces the selection signal causing the selector to select the added signals in response to the first level of the output signal and causing the selector to select the subtracted signals in response to the second level of the output signal.

Abstract: A pressure sensor includes a body made of semiconductor material having a first type of conductivity and a pressure-sensitive structure having the first type of conductivity defining a suspended membrane. One or more piezoresistive elements having a second type of conductivity (P) are formed in the suspended membrane. The piezoresistive elements form, with the pressure-sensitive structure, respective junction diodes. A temperature sensing method includes: generating a first current between conduction terminals common to the junction diodes; detecting a first voltage value between the common conduction terminals when the first current is supplied; and correlating the detected first voltage value to a value of temperature of the diodes. The temperature value thus calculated can be used for correcting the voltage signal generated at output by the pressure sensor when the latter is operated for sensing an applied outside pressure which deforms the suspended membrane.
