Abstract: A pseudo-differential switched-capacitor circuit using integrator-based common-mode stabilization technique is disclosed. A pseudo-differential switched-capacitor circuit with the differential floating sampling (DFS) technique has a common-mode gain value of one (1). An integrator is electrically coupled to the differential positive/negative outputs of the DFS circuit, and the integrator feeds back integrator output to the DFS circuit by detecting common-mode voltage disturbance at the differential positive output (Vout+) and negative output (Vout−), thereby stabilizing output common-mode level of the differential positive output (Vout+) and negative output (Vout−) at a desirable level.

Abstract: A successive approximation register (SAR) analog-to-digital converter (ADC) is disclosed. A first and second capacitor DACs receive a first and second input signals respectively. A first coarse comparator compares an output of the first capacitor DAC with a window reference voltage, a second coarse comparator compares an output of the second capacitor DAC with the window reference voltage, and a fine comparator compares the output of the first capacitor DAC with the output of the second capacitor DAC. A SAR controller receives outputs of the first and second coarse comparators to determine whether the outputs of the first and second capacitor DACs are within a predictive window determined by the window reference voltage. The SAR controller bypasses at least one phase of analog-to-digital conversion of the SAR ADC when the outputs of the first capacitor DAC and the second capacitor DAC are determined to be within the predictive window. The SAR controller decodes the outputs of the first and second coarse comparators and the fine comparator to obtain a converted output of the SAR ADC.

Abstract: A metal-oxide-metal (MOM) capacitor able to reduce area of capacitor arrays is revealed. The MOM capacitor mainly includes at least three parallel conducting layers. Each parallel conducting layer consists of a first conductive plate, a second conductive plate disposed around the first conductive plate. There is a preset distance between the first conductive plate and the second conductive plate. The first conductive plates are electrically connected by at least one first via while the second conductive plates are electrically connected by at least one second via. Thereby, while being applied to capacitor arrays, the second conductive plates of the two adjacent MOM capacitors are connected together and shared with each other, so as to significantly reduce area of the capacitor array, improve circuit density and further optimize the layout efficiency of the chip design.

Abstract: A capacitance mismatch calibrating method for a successive approximation register ADC which includes at least one array of capacitors is provided. The method includes the following steps: firstly, at least two compensating capacitors are configured. A capacitor from the array of capacitors is selected as a capacitor-under-test. Then, the terminal voltages on the terminals of the array of capacitors and on the terminals of the compensating capacitors are determined. A first comparison voltage is outputted based on the determined terminal voltages. Afterwards, a sequence of comparisons is controlled based on the first comparison voltage and a second comparison voltage to output a sequence of corresponding digital bits. Finally, a calibration value is calculated to calibrate the value of a capacitor-under-test according to the digital bits.
