Patent ID: 8096707

Claim:
A thermal sensor device comprising: a front-end component to sense a temperature on a die, the front-end component including an analog chopper, an array of current sources, a dynamic element matching (DEM) device and two diodes each to sense the temperature on the die, the DEM device to couple to the array of current sources and to the analog chopper, the front-end component to provide analog signals at two output nodes based on currents through the two diodes, an output of the chopper and a first one of the diodes being coupled to a first one of the output nodes, and an output of the chopper and a second one of the diodes being coupled to a second one of the output nodes; an analog-to-digital converter to receive the analog signals from the front-end component and to provide a digital output signal; and a digital backend to receive the digital output signal from the analog-to-digital converter, to demodulate the received digital output signal in a digital domain and to provide a calculated temperature.
