摘要： Provided is a pipeline analog-to-digital converter (ADC) without a front-end sample-and-hold amplifier (SHA). To minimize a sampling error occurring between a flash ADC and a multiplying digital-to-analog converter (MDAC) of a first sub-ranging ADC due to removal of a front-end SHA, a delay time of a preamplifier included in the flash ADC is calculated, and the flash ADC samples an analog input signal later by the delay time than the MDAC. Accordingly, the pipeline ADC can minimize a sampling error without using a front-end SHA, and its chip area and power consumption can be reduced.

摘要： A digital-to-analog converter (DAC) is provided. The DAC includes a positive converter, a negative converter, and a comparator for receiving outputs of the positive converter and the negative converter, comparing the outputs with a reference voltage, and generating an output voltage. Each of the positive converter and the negative converter includes an upper-bit converter including a plurality of bit capacitors corresponding to respective upper bits, a lower-bit converter including a plurality of bit capacitors corresponding to respective lower bits, and a coupling capacitor for connecting the upper-bit converter with the lower-bit converter in series. Each of the positive converter and the negative converter receives a bias voltage to have a uniform offset when converting the respective bits. Accordingly, it is possible to obtain a high resolution using a small area. Also, the number of capacitors can be reduced, and the capacitance of a unit capacitor can be maximized. Consequently, it is possible to minimize heat noise and device mismatching.

摘要： A band-gap reference voltage generator is provided. N-channel metal oxide semiconductor (NMOS) transistors are respectively connected to bipolar transistors in parallel. A Complementary To Absolute Temperature (CTAT) voltage that is inversely proportional to absolute temperature is reduced by a threshold voltage of the NMOS transistor. A weight for a temperature coefficient of a Proportional To Absolute Temperature (PTAT) voltage that is directly proportional to absolute temperature is reduced and a resistance ratio for a temperature coefficient of 0 is reduced by about ½, thereby miniaturizing the band-gap reference voltage generator. A reference voltage lower than or equal to 1 V can be provided by resistors respectively connected to the bipolar transistors in parallel.

The read-out circuit includes an amplification unit and a feedback resistor. The amplification unit has an amplification gain between 0 and 1.

摘要： A successive approximation register (SAR) analog-digital converter (ADC) and a method of driving the same are provided. The SAR ADC includes a first converting unit including a bit capacitor array corresponding to the number of bits and a correction capacitor array, a comparator outputting a high or low voltage corresponding to each capacitor according to an output voltage of the converting unit, and a correction unit correcting the output of the bit capacitor according to the output of the correction capacitor array among the high or low output of the comparator. Therefore, two bits having the same capacitance as a least significant bit (LSB) enable a digital output error to be corrected, so that a spurious free dynamic range (SFDR) of the signal converter is increased, and a signal to noise and distortion ratio (SNDR) of an output signal is improved.
