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 11):
The method of  claim 10 , wherein the comparator circuit includes the amplifier circuit coupled to a latch circuit, and a primary capacitor switchably coupled to an input of the latch circuit, and\n wherein reconfiguring the comparator circuit as an amplifier circuit to process the quantization error and applying the processed quantization error to a noise-shaping feedback circuit coupled to an input of the ADC includes: amplifying a residual voltage at an input of the amplifier circuit representing the quantization error and controlling a storage of a charge representing the residual voltage on the primary capacitor; transferring the charge to a secondary capacitor; and after the conversion phase and before the acquisition phase, applying a voltage representing a cumulative charge stored on the secondary capacitor to the noise-shaping feedback circuit, wherein the voltage representing a cumulative charge stored on the secondary capacitor includes the residual voltage.
