Abstract
A signal path, such as receiver signal path of a mobile station, includes an analog to digital converter (ADC) for representing an input signal as n-bits, the n-bit representation including a DC offset component. The signal path also includes a summing node having a first input for inputting the n-bit output of the ADC and a second input for inputting a k-bit representation of a DC offset component compensation value, where k=n+m, where m is a number of bits that represent a value smaller than one least significant bit (LSB) of said n-bit representation. The summing node operates to subtract the value appearing at the second input from the value appearing at the first input, and outputs a k-bit DC offset compensated value.
