Abstract:
An integrated circuit comprising:a switched capacitor for simulating an ohmic resistor and having one of its plates coupled with a signal input via a transistor switch having a source, a drain and a gate, the gate thereof being fed with a control signal in the form of a pulse train of predetermined frequency, with a compensation component being located between the transistor switch and one capacitor plate of said switched capacitor, which is controlled in phase opposition to the transistor switch so as to compensate the effective parasitic capacitance between the gate and the drain or between the gate and the source of the transistor switch, wherein the compensation component being composed of an incomplete transistor structure having a gate adjoining a drain region or a source region of the transistor switch to which said one plate of the switched capacitor is connected.
