    摘要: A circuit arrangement for regulating a parameter (e.g., duty cycle) of an electrical signal, generated by a circuit component. The regulating device includes a first integrator, which is supplied with the output signal from the circuit component, and a second integrator, which is supplied with the output signal from the first integrator. The second integrator has an operational amplifier having an inverting input, a noninverting input and an output, and the output is fed back to the inverting input via a feedback path. The inverting input receives the output signal from the first integrator. The noninverting input receives a reference signal. The output of the operational amplifier is fed back to the inverting input via a series circuit including a capacitor and a resistor. The output of the second operational amplifier provides an output signal from the regulating device, which is supplied to the circuit component as a controlled variable.

    摘要: Circuitry separates a modulation signal into digital sign and magnitude signal components. The digital magnitude signal is converted to an analog magnitude signal. The analog magnitude signal is the mixed with an in-phase or quadrature carrier signal under the influence of the digital sign signal and routed to a driver output stage.
