Abstract

Convertidor temperatura-a-digital de alta precisión con bajo consumo de potencia.#Se proporciona un convertidor de temperatura-a-digital de alta precisión con bajo consumo de potencia. La potencia es obtenida a partir de ondas inalámbricas. También se proporciona un método de medición de la temperatura asociado al convertidor. El convertidor comprende un termistor RTH (1510) cuya resistencia depende de la temperatura; un resistor RP (1530); un resistor RS (1520); un condensador de integración CINT (1540), invariables con la temperatura; un circuito de lectura y conversión (1300) que mide la resistencia del termistor y convierte dicho valor representativo de la temperatura, en un código digital para su posterior procesado. El método comprende cuatro pasos tal que la resistencia del termistor RTH es proporcional a un término dependiente de la temperatura NTEMP.High-precision digital-to-digital converter with low power consumption. # A high-precision digital-to-digital converter with low power consumption is provided. The power is obtained from wireless waves. A temperature measurement method associated with the converter is also provided. The converter comprises an RTH thermistor (1510) whose resistance depends on the temperature; an RP resistor (1530); an RS resistor (1520); a CINT integration capacitor (1540), invariable with temperature; a reading and conversion circuit (1300) that measures the resistance of the thermistor and converts said temperature representative value into a digital code for further processing. The method comprises four steps such that the resistance of the RTH thermistor is proportional to a term dependent on the NTEMP temperature.
