Classification: CPC H | IPC H

Claim 0:
1. An analog-to-digital converter (ADC) circuit to generate a digital output signal, the ADC circuit comprising:
an oversampled ADC circuit having an input coupled to receive an analog input signal and generate a first digital output signal, the oversampled ADC including:
a chop switch that receives and is controlled by a variable frequency chop signal; and
a chop signal generating circuit to generate the variable frequency chop signal;
a sample rate converter circuit to receive the first digital output signal at a first sample rate and generate a second digital output signal at a second sample rate; and
a digital filter circuit including a decimator to process and decimate the second digital output signal and generate a filtered digital output signal.
