In some embodiments, the stacked integrated chip structure has a main integrated chip and a secondary integrated chip located on an interposer wafer. The main integrated chip has a reference voltage source that generates a bias current. The secondary integrated chip has a second thermal diode that receives the bias current and based thereupon generates a second thermal sensed voltage and a second reference voltage that is proportional to a temperature of the secondary integrated chip. A digital thermal sensor within the main integrated chip determines a temperature of the secondary integrated chip based upon as comparison of the second thermal sensed voltage and the reference voltage. | 2014-04-03 |
20140092940 | TEMPERATURE SENSOR - A temperature sensor includes a pair of element electrode wires extending rearward from a temperature-sensing portion. A pair of second electrode wires are welded to the element s electrode wires, and made of a kind of metal having a different thermal expansion coefficient than the element electrode wires. Each second electrode wire includes an overlap section overlapping with an overlap section of the corresponding element electrode wire over an overlap region in a longitudinal direction in which the overlap sections of the each second electrode wire and element electrode wire extend longitudinally. The overlap section of each second electrode wire is welded to the overlap section of the corresponding element electrode wire at weld zones arranged in the longitudinal direction, which include: one at a front-side end of the overlap region; and another at a rear-side end of the overlap region. | 2014-04-03 |
20140092941 | PROCESSOR FOR A RADIO CIRCUIT - A processor for a radio circuit is disclosed. The processor includes a full spectrum receiver and a white space classifier. The full spectrum receiver is configured to receive an analogue radio signal comprising multiple channels within a frequency band and transform the analogue radio signal to a digital radio signal. The full spectrum receiver is also configured to transform the digital radio signal from a time domain signal to a frequency domain signal. The white space classifier is configured to identify an unused channel within the frequency band using the frequency domain signal derived from the analogue radio signal. | 2014-04-03 |
20140092942 | METHODS AND APPARATUSES USING FILTER BANKS FOR MULTI-CARRIER SPREAD-SPECTRUM SIGNALS - A transmitter includes a synthesis filter bank to spread a data symbol to a plurality of frequencies by encoding the data symbol on each frequency, apply a common pulse-shaping filter, and apply gains to the frequencies such that a power level of each frequency is less than a noise level of other communication signals within the spectrum. Each frequency is modulated onto a different evenly spaced subcarrier. A demodulator in a receiver converts a radio frequency input to a spread-spectrum signal in a baseband. A matched filter filters the spread-spectrum signal with a common filter having characteristics matched to the synthesis filter bank in the transmitter by filtering each frequency to generate a sequence of narrow pulses. A carrier recovery unit generates control signals responsive to the sequence of narrow pulses suitable for generating a phase-locked loop between the demodulator, the matched filter, and the carrier recovery unit. | 2014-04-03 |
