The semiconductor communication device includes a Delta-Sigma analog-to-digital converter that converts input analog signals to digital signals, a power detecting unit that detects signal power of the digital signals, a gain control unit that changes a gain setting of analog signals to be input to the Delta-Sigma analog-to-digital converter depending on the signal power of the digital signals, and a dither signal control unit that causes the Delta-Sigma analog-to-digital converter to selectively add the dither signal when the gain setting changes. | 01-23-2014 |
20140203958 | PASSIVE AMPLIFICATION CIRCUIT AND ANALOG-DIGITAL CONVERTOR - A differential signal is amplified by passive amplification which does not a reference of a common-mode voltage. At this time, the voltage of the differential signal is passive-amplified twice before carrying out a successive approximation type analog-digital conversion operation. The passive amplification is attained by providing a plurality of capacitances which carry out a sampling operation, and switching these connection relation by using switches. Without being accompanied by the increase of the consumed power and the chip size, an influence by the noise of s comparator is reduced to a half so that the effective resolution can be increased for one bit. | 07-24-2014 |
20140253352 | SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE - A digital-correction-type A/D converter which is a charge sharing type and performing successive approximation is realized in a small area. The A/D converter is configured with an A/D conversion unit which is a charge sharing type and performing successive approximation, a digital correction unit which receives a digital output of the A/D conversion unit and performs digital correction to the digital output, and a holding unit which holds a test signal. A test signal of a common value from the holding unit is inputted into the A/D conversion unit in the first period and the second period. The A/D conversion correction coefficient for the digital correction unit is calculated on the basis of the digital correction result of the digital correction unit in the first period, and the digital correction result of the digital correction unit in the second period. | 09-11-2014 |
20140333459 | ELECTRONIC SYSTEM AND OPERATING METHOD THEREOF - To compensate for non-linearity of an AD conversion unit and non-linearity of a DA conversion unit in an electronic system including the DA conversion unit and the AD conversion unit, an electronic system includes an A/D conversion unit, a D/A conversion unit, an AD conversion compensation unit, a DA conversion compensation unit, and a calibration unit. During a calibration operation period, the calibration unit sets an operating characteristic of the AD conversion compensation unit and an operating characteristic of the DA conversion compensation unit. The operating characteristic of the AD conversion compensation unit set during the calibration operation period compensates for non-linearity of AD conversion of the A/D conversion unit. The operating characteristic of the DA conversion compensation unit set during the calibration operation period compensates for non-linearity of DA conversion of the D/A conversion unit. | 11-13-2014 |
