Abstract: An electronic circuit includes a reference ADC, a delay circuit, and a main ADC. The reference ADC converts an input signal to an upper bit string of output data, in response to a reference clock. The delay circuit delays a source clock by a delay time to output a main clock. The main ADC converts the input signal to a lower bit string of the output data, in response to the main clock. When a value of the most significant bit included in the lower bit string is identical to a value of the bit which is adjacent to the most significant bit and lower than the most significant bit, the delay time is adjusted based on a direction in which a level of the input signal is changed and the value of the most significant bit of the lower bit string.

Abstract: An analog-to-digital converter includes: a sample/hold circuit, which samples an analog signal, and outputs a first voltage; a digital-to-analog conversion circuit, which converts a digital signal to output a second voltage; an amplifier, which amplifies the first voltage and the second voltage; a noise shaping filter, which integrates a residual voltage corresponding to a difference between the amplified first voltage and the amplified second voltage, and generates a first integration voltage and a second integration voltage; a comparator, which compares a sum of the amplified first voltage, the first integration voltage, and the second integration voltage with the amplified second voltage; and a SAR logic, which outputs the digital signal according to a comparison result of the comparator, and controls the digital-to-analog conversion circuit.
