Circuit arrangement for e.g. mobile telephone, has regulation unit coupled with signal processing unit to provide digital regulation signal for regulation of analog output signal depending on analog output signal and ramp signal

摘要

The arrangement has a signal processing unit (5) for processing an input signal (Sin) into an analog output signal (Sout). A regulation unit (50) is coupled with the signal processing unit to provide a digital regulation signal (Sdr) for the regulation of the analog output signal depending on the analog output signal. A digital-analog converter (69) is coupled with the regulation unit for the conversion of the digital regulation signal into an analog regulation signal (Sar). The regulation unit provides the digital regulation signal depending on a ramp signal (Sr). Independent claims are also included for the following: (1) a method for manufacturing a circuit arrangement (2) a method for adjusting an analog output signal (3) an arrangement for accomplishing a method for adjusting an analog output signal (4) a computer program product for controlling of a micro controller to perform a method for adjusting an analog output signal.
