摘要： A time-interleaved bandpass delta-sigma modulator is developed which includes a first adder and a second adder and a comparator. An input signal is transmitted to the first adder according to the clock frequency of each channel block, and an n channel block output un of the first adder is transmitted to the first adder and the second adder of an n+2 channel block, and an n block output vn of the second adder is transmitted to the second adder of an n+2 block, and an output yn that passes through an n block comparator is transmitted to the first adder and the second adder of an n+2 block. Therefore, a modulator sequentially receives output from the comparator of each block for generating the final output y.

摘要： An analog-to-digital converter includes a comparison signal generation unit and a control unit. The comparison signal generation unit determines a logic level of a comparison signal by comparing an input signal with a selected reference signal based on a switch control signal in a first comparison mode, and by comparing a difference voltage with a ramp signal based on the switch control signal in a second comparison mode. The difference voltage is generated based on the input signal and the selected reference signal such that a level of the difference voltage is lower than a fine voltage level corresponding to a voltage level of the selected reference signal in the second comparison mode. The control unit generates the switch control signal based on the comparison signal and a mode selection signal.
