Abstract
An electric filtering circuitry for filtering ripples of an input signal, includes an input terminal for applying the input signal, an output terminal to provide an output signal, and a forward path including a clocked integrator circuit and a clocked sample-and-hold or track-and-hold circuit. The electric filtering circuitry also includes a summing node that receives the input signal and the output signal, and provides a difference signal. The clocked integrator circuit has an input side connected to the summing node to receive the difference signal, and an output side to provide an integrator output signal. The clocked sample-and-hold or track-and-hold circuit has an input side to receive the integrator output signal, and an output side to provide a sample-and-hold or track-and-hold output signal. The output side of the sample-and-hold or track-and-hold circuit is coupled to the output terminal. A feedback path is between the output terminal and the summing node.
