Abstract

Circuito electrónico con magnitud eléctrica de salida dependiente de la diferencia de tensión de dos nodos de entrada y de la diferencia de temperatura de dos de sus dispositivos.#La presente invención describe un circuito electrónico cuya magnitud eléctrica de salida depende de la diferencia de tensión de dos de los nodos de entrada del mismo así como de la diferencia de temperatura de dos de sus dispositivos internos. La figura 1 muestra el símbolo del circuito electrónico. Éste tiene como entradas eléctricas dos entradas en tensión (2) y (3) y dos entradas de alimentación (6) y (7), y como salida tiene un nodo (1). Además, tiene dos dispositivos internos (4) y (5) cuya diferencia de temperaturas influirá de forma directa en el valor de la magnitud eléctrica del nodo de salida. En el circuito de la presente invención la variación de la magnitud eléctrica de la salida (1) depende de la diferencia de tensión de los dos nodos de entrada (2) y (3) así como de la diferencia de temperaturas de los dispositivos internos (4) y (5).Electronic circuit with electrical output magnitude dependent on the voltage difference of two input nodes and the temperature difference of two of its devices. # The present invention describes an electronic circuit whose electrical output magnitude depends on the voltage difference of two of the same input nodes as well as the temperature difference of two of its internal devices. Figure 1 shows the electronic circuit symbol. This has two voltage inputs (2) and (3) and two power inputs (6) and (7) as electrical inputs, and has a node (1) as output. In addition, it has two internal devices (4) and (5) whose temperature difference will directly influence the value of the electrical magnitude of the output node. In the circuit of the present invention the variation of the electrical magnitude of the output (1) depends on the voltage difference of the two input nodes (2) and (3) as well as the temperature difference of the internal devices ( 4) and (5).
