摘要： A system for regulating the transfer impedance of a plurality of current-to-voltage converters to a substantially equal value includes a reference voltage source and a reference impedance for providing a reference current. A reference current-to-voltage converter is responsive to the reference current and provides an output voltage. A comparator is responsive to the reference voltage and the output voltage and provides a control signal to the reference current-to-voltage converter and to all the other current-to-voltage converters to maintain the transfer impedance of all the current-to-voltage converters constant.

摘要： Conventional integrable differential amplifiers have implanted resistors as load resistors, the limited size of which represents a barrier for the minimization of current consumption. In accordance with the present invention, the load resistors are replaced by load elements that represent non-linear two-terminal elements such as diodes, the potential at these load elements is held constant via a control loop by a controlling element such as a control transistor. This allows the current consumption of differential amplifier stages to be reduced to the order of magnitude of the residual current without increasing the area required for integration of the circuit.

摘要： A heterodyne receiver operating on the principle of synchronous modulation for time-signal reception where a first mixer is driven by the first phase-locking loop which is fed from a reference frequency source and a switchable precharging value. By means of switched frequency dividers and the precharging values, internationally different clock frequencies (JP: 40 kHz; USA/GB: 60 kHz; EU/D: 77.5 kHz) can be processed and converted to the intermediate frequencies. These are then synchronously demodulated by means of a second mixer which receives its signal from the second phase-locking loop that is driven through the intermediate frequency signal via the phase comparator, and also through the control signal of the phase-locking loop, so that only residual error adjustment need be performed.

摘要： A folding amplifier is proposed for the construction of an A/D converter to which a current signal is fed as the input signal and from which a current difference signal is derived using a reference current. This current difference signal is fed to a first current-controlled current source, which is designed as a current mirror, and also to a second current-controlled current source, whereby the first current source takes over this current when the current difference signal has a positive sign and if the current difference signal has a negative sign the second current source takes over this current. The outputs of the first and second current-controlled current sources are fed to the output of the folding amplifier. Preferably, this folding amplifier is provided with a third current-controlled current source with sign reversal whose input is connected to the outputs of the first and second current sources and whose output is a V-shaped output current signal.
