Abstract
In a device, a pulse modulation switching logic is provided to generate switching signals of a pulse modulator so as to generate a pulse modulated signal with a first pulse modulation control parameter and a second pulse modulation control parameter. The first pulse modulation control parameter is controlled on the basis of a first control signal, and the second pulse modulation control parameter is controlled on the basis of a second control signal. A first control loop is provided to generate the first control signal from an output signal derived from the pulse modulated signal. A second control loop is provided to generate the second control signal on the basis of the output signal. The first and second control signals are applied to concurrently control the first and second pulse modulation control parameters.
