Abstract:
A pipeline analog-to-digital converter (ADC) includes a hybrid multiplying digital-to-analog converter (MDAC) that includes multiple digital-to-analog converters (DACs), an amplifier, and a conversion circuit. The multiple DACs function in a pipelined manner such that each DAC receives an analog input signal in different cycles of a clock signal and generates a corresponding analog output signal. The amplifier amplifies each analog output signal to generate a corresponding amplified analog signal in different cycles of the clock signal. The conversion circuit successively approximates each analog output signal to generate multiple digital signals. Thus, a digital output signal of the pipeline ADC is generated based on the corresponding amplified analog signal and at least one of the multiple digital signals. The pipeline ADC utilizes one cycle for performing each of sampling, conversion, and amplification operations, which results into low power consumption by the pipeline ADC.
