The integrator has a transconductance amplifier (V) whose output is fed back via an integration capacitance (Ci) to its inverting input and with a first reference voltage applied to its non-inverting input. A first current source with a parasitic parallel capacitance has one terminal at reference potential (V2) and another connected via an Ohmic device to a second reference voltage (V1). The Ohmic device is a potential divider with a resistance and another circuit stage, e.g. a switched capacitance or current source, whose junction is connected to the amplifier's inverting input. |
