    摘要: A supply power can be fed in at a circuit arrangement for supplying power to, and clocking, clocked loads. The circuit arrangement provides a clock signal at a frequency and a supply voltage, the frequency and/or the supply voltage being able to be controlled by the circuit arrangement in such a manner that a power tapped off at the output and the supply power fed in are in a predefined relationship.

    摘要: A current-supply circuit includes a regulation transistor. The regulation transistor is formed to regulate, based on a first supply voltage present on a first supply-voltage feed line, a second supply voltage present on a second supply-voltage feed line. The regulation transistor provides a supply current to the second supply-voltage feed line. The voltage-supply circuit further includes an operating-point determiner, which is formed to determine, based on information that is a measure for the supply current, whether the regulation transistor is at a low operating point at which the supply current is below a determined current. The voltage-supply circuit further includes a preventer that is formed to prevent, starting from the low operating point, a rise of the supply current by at least a predetermined current amount from occurring within a predetermined period.

    摘要: A signal processing circuit including a demodulator having an input for receiving a received signal which includes falling and rising signal edges, and an output for outputting a demodulated received signal which, with signal edges of the received signal, includes transitions from a first level to a second level or vice versa, wherein times of the transitions depend on steepnesses of the signal edges. Additionally, the circuit includes a signal generator having an input for receiving the demodulated received signal and coupled to the output of the demodulator, and an output for outputting a corrected demodulated received signal which includes transitions, the times of which relative to the times of the transitions of the demodulated received signal are set based on a reference signal to reduce influences of the steepnesses of the falling and rising signal edges in the corrected demodulated received signal relative to the demodulated received signal.
