Title
(EN) ELECTRO-THERMAL BASED DEVICE AND METHOD FOR OPERATING A HEATER
(FR) DISPOSITIF ÉLECTRO-THERMIQUE ET PROCÉDÉ DE FONCTIONNEMENT D'UN DISPOSITIF DE CHAUFFAGE
Abstract
(EN)
An electro-thermal based device comprises a heater (11), a readout circuit (14), a digital controller (16) having a first input (17) coupled to a first output (18) of the readout circuit (14), and a digital sigma-delta modulator (19) having a first input (20) coupled to an output (21) of the digital controller (16) and an output (22) coupled to the heater (11).
(FR)
