    • A discrete time filter includes a plurality of sampling cells and a first dummy sampling cell. Each of the sampling cells performs a current mode sampling operation based on current input to an input terminal in response to a corresponding one of a plurality of sampling clock signals and is reset in response to a corresponding one of the plurality of sampling clock signals and a first dummy sampling clocks. The first dummy sampling cell alternately performs with the first sampling cell the current mode sampling operation based on current input to the input terminal in response to the first dummy sampling clock signal and is alternately reset with the first sampling cell in response to the first sampling clock signal.

    • A folding analog-to-digital converter including: a reference voltage generator, a track-and-hold circuit and a first pre-amplification circuit. The reference voltage generator generates a plurality of reference voltages. The track-and-hold circuit generates a sampling control signal having a voltage level lower than or equal to a level of a power supply voltage by maintaining an initial level of a boost capacitor voltage at a level lower than a level of a power supply voltage, and samples and holds an input voltage signal in response to the generated sampling control signal to generate a sampled signal. The first pre-amplification circuit amplifies each of voltage differences between the sampled signal and each of the plurality of reference voltages.
