摘要： A circuit arrangement (16) for producing a D.C. current, includes a feedback loop for producing a reference current from an output terminal (27) with a negative temperature coefficient. The feedback loop includes a current-source stage (17, 18) which feeds a current mirror stage (19, 20, 21) in response to a measuring current supplied from a current bank (24, 25, 28, 29), which also produces the output reference current. The output of the current mirror stage (19, 20, 21) drives a working impedance formed by the main current path of a transistor 22, across which a control voltage is developed which is applied to a control input (23) of the current bank (24, 25, 28, 29). The circuit arrangement is advantageously combined with a reference current source (1) arranged as a bandgap circuit for producing a reference current on an output terminal (2) with a positive temperature coefficient, by enabling the user to select a current reference with either a positive or negative temperature coefficient. Further, the respective reference current outputs with positive and negative temperature coefficients, properly dimensioned, may be combined to provide an output current from a common output terminal (35) which is independent of temperature in a predefined temperature range.

摘要： The invention relates to a circuit comprising an amplifier with bipolar transistors, which amplifier is fed by a signal source with a complex internal resistance and which has a signal negative feedback path connecting the amplifier output to the signal source. For reducing the noise, especially the input noise current which is particularly predominant in circuits of this kind which have a sufficiently large source impedance, a reactance network is arranged between the amplifier and the signal source. The network, in connection with the signal source and the negative feedback path, constitutes a filter which is parallel to the amplifier input and which has at least a series resonance frequency within the signal frequency range.

摘要： Circuit arrangement for shifting the phase of an input signal, which circuit arrangement consists of two branches whose two output signals are 90° phase-shifted, and use of this phase shifter in a circuit arrangement for suppressing the mirror frequency. The filter systems in the two branches of the phase shifter are implemented in such a way that the phase difference between these two branches is 90°, independent of the frequency of the input signal. In the mirror frequency circuit, a frequency band is amplified or blanked during transmission. The base frequency BF constitutes the center of the frequency band. The amplitude difference is small in the solutions according to the invention. The amplitude difference is improved when the two 90° phase-shifted signals are matched or substantially equalized as regards their amplitude. The matching is performed in that the two signals are rectified and subsequently subtracted from each other. The result is supplied to an integrator whose output signal, together with a reference signal, constitutes the control value. This results in a substantially ideal suppression of the mirror frequency. The circuit arrangement can be used in a radio or television receiver.

摘要： The invention relates to an anti-demodulator circuit which is fundamentally built up in the same way as a demodulator circuit but, instead of a bandpass filter as generally used in a demodulator, comprises a notch filter which receives an input signal comprising a useful signal and an interference signal, and generates a filtered signal. The notch filter has a center frequency which approximately corresponds to the frequency of the input signal so as to suppress at least a part of the useful signal. The anti-demodulator circuit further comprises a mixer circuit which receives the filtered signal and a phase-shifted input signal and supplies a demodulated output signal which substantially corresponds to the interference signal.The invention can be particularly used in connection with a filtering device for suppressing interference signals based on adjacent channel disturbances in FM radios, in which the bandwidth of the filtering device is controlled in dependence upon the output signal of the anti-demodulator circuit.
