DISPOSITIVO DI SENSING DI TEMPERATURA E METODO PER GENERARE UN SEGNALE RAPPRESENTATIVO DELLA TEMPERATURA DI UN AMBIENTE |
摘要 |
<p>A sensing device includes a first current mirror configured to mirror a current flowing through a thermistor, a second current mirror configured to mirror a current flowing through a reference resistor a comparator configured to compare voltages on the thermistor and the resistor, and a counter configured to generate a control signal representative of a temperature difference based on the comparison. The control signal controls a mirroring ratio of the second current mirror. The sensing device may be employed to generate a droop current of a voltage regulator.</p> |
