Abstract:
Some or all of a comparator circuit of an analog-to-digital converter (ADC) circuit can be efficiently repurposed or reused for residue amplification for efficient noise-shaping, e.g., in a noise-shaping feedback configuration. A preamplifier portion of a comparator circuit in an oversampling ADC can be re-purposed to provide an amplifier to amplify or otherwise modify a residue left after the bit trials of a conversion cycle. The amplified or modified residue can then be used elsewhere, for example, for noise-shaping by applying a noise transfer function (NTF), a result of which can then be fed back (e.g., summed with the next sampled input at an input of the comparator circuit for use in the N bit trials of the next ADC cycle).

Claim (Index 1):
An analog-to-digital converter (ADC) circuit comprising:\n a digital-to-analog converter (DAC) circuit to receive a sampled input signal; a comparator circuit having first and second inputs, the first input coupled to an output of the DAC circuit and configured to compare the output of the DAC circuit at the first input to a voltage at the second input; a noise-shaping feedback circuit coupled to an input of the comparator circuit; and a control circuit coupled to the output of the comparator circuit and an input of the DAC circuit, wherein, after a conversion phase and before an acquisition phase, the control circuit reconfigures the comparator circuit to operate as an amplifier circuit to process a quantization error at the DAC circuit after all bit trials of the sampled input signal and apply the processed quantization error to the noise-shaping feedback circuit coupled to an input of the ADC circuit.
