摘要： An object is to provide a noise removing circuit that can be integrally formed on a semiconductor substrate and can improve the accuracy of noise component removal. The noise removing circuit comprises a highpass filter detecting a noise component included in an input signal, a pulse generating circuit generating a pulse signal corresponding to the detected noise component, an analog delaying circuit 252 delaying the input signal, and an outputting circuit removing the noise component included in the delayed signal according to the output timing of the pulse signal. The analog delaying circuit 252 delays the output timing of the input signal by making switches 51 to 56 electrically continuous in a sequential order, by holding the voltage of the input signal at each time point in a plurality of capacitors 81 to 86, and by extracting the held voltage before being updated by making switches 61 to 66 electrically continuous.

摘要： A method and circuitry for time-sharing a digitally-programmable capacitive element, particularly in conjunction with a switched-capacitor filter circuit. The method includes: selecting a first capacitance value for the capacitive element; initializing the charge on the capacitive element; connecting the capacitive element to first preselected nodes of an electronic circuit; disconnecting the capacitive element from the first preselected nodes of after any charge transfer has substantially been completed; changing the capacitance of the capacitive element to a new desired value; initializing the charge on the capacitive element; and then connecting the capacitive element to other preselected nodes of the electronic circuit. A biquad switched-capacitor filter circuit is configured to use such method in its operation.

摘要： The switched-capacitance amplifier comprises n capacitors C.sub.11 to C.sub.1n which are periodically switched in parallel and in series, the n parallel-switched capacitors being charged simultaneously by the same voltage V.sub.E. An amplified voltage n.times.V.sub.E is obtained between the end terminals A and B of the n series-switched capacitors. Periodic switching of the n capacitors in parallel and in series is performed by means of MOS transistors T.sub.11 to T.sub.1(2n-1) and T.sub.21 to T.sub.2(n-1) which operate in the switching mode. The n capacitors and the MOS transistors are integrated on the same semiconductor substrate.

摘要： A bandpass filter is disclosed which includes a low-pass filter and an analog delay circuit in which the delay time is set by a clock signal. THe analog delay circuit samples the voltage of the low-pass filter capacitor and delays the sampled voltage according to the clock signal. The output of the analog delay circuit is then used to equalize within a certain period of time the voltage of the low-pass filter capacitor. The analog delay circuit may consist of an integrated circuit BBD (Bucket Brigade Device) or CCD (Charge Coupled Device).
