A signal processor and a method for processing an input signal are presented. The signal
processor is adapted to clip an oversampled input signal without introducing noise in the …

To address non-linearity, an on-chip linearization scheme is implemented along with an
analog-to-digital converter (ADC) to measure and correct/tune for non-linearities and/or …

Non-idealities of input circuitry of a receiver signal chain can significantly degrade the
overall performance of the receiver signal chain. To meet high performance requirements …

(57) ABSTRACT A signal processing structure and method are presented. A first digital filter
operates on received sigma-delta modulated (SDM) input signals. A second pre-processing …

(57) ABSTRACT A digital filter and a method for filtering a pulse density modulation (PDM)
signal are presented. The digital filter has a first filter circuit to receive an input signal with …

A quantizer and a method for a sigma-delta modulator circuit that may be used as a
component within an adaptive-noise cancelling headphone are presented. An apparatus …

An anti-noise signal generator and a method of generating an anti-noise signal are
presented. The anti-noise generator includes a first microphone input to receive a first sigma …

A digital filter and a method for filtering a pulse density modulation (PDM) signal are
presented. The digital filter has a first filter circuit to receive an input signal with input values …

A digital filter for filtering a pulse density modulation (PDM) signal is presented. The filter has
a first filter circuit to receive an input signal and to provide a filtered input signal at …

An active noise cancellation (ANC) system is presented. The ANC system includes a
transducer; a first microphone; and a first adaptive filter coupled to a calculator. The …
