Abstract: An amplifier and method of setting the amplifier is presented. The amplifier is set by setting a mean value between voltage values at first and second outputs of the amplifier. The mean value is pulled towards a certain voltage potential. A circuit node is coupled to the first and to the second output. The circuit node is connected, via at least one resistor and a respective switch, to the certain voltage potential assigned to the respective resistor.

Abstract: Scrambling devices (15) rotate the digital output signal of the sigma delta encoder (1) as a function of a computed current pointer. Pointer computation pipeline mechanisms (16) calculate the value of the current pointer P(n+1) as a function of a preceding pointer P(n) and preceding output data D(n). The preceding pointer and the preceding output data are delayed by at least one clock cycle. Preferably the current pointer is computed from the sum of the preceding pointer and preceding output data. Independent claims are included for : (1) a sigma-delta analog-digital converter for converting an applied analog input signal into digital output data; and (2) a method for calculating a current value pointer for a data-weighting device forming an average value within a sigma-delta analog-digital converter.
