Abstract
A converter can include a number of time-to-voltage converters (TVCs) each receiving an input time-domain signal. The input time-domain signal can represent a different sample than input time-domain signals of the other TVCs. The converter can also include a capacitive element coupled to outputs of the TVCs to receive a combined output signal of the TVCs. The capacitive element can provide an input capacitance of an analog-to-digital converter (ADC). Other methods and apparatuses are described.
Claims21
A converter comprising:
- a plurality of time-to-voltage converters (TVCs), a TVC of the plurality configured to receive an input time-domain signal, the input time-domain signal representing a different sample than input time-domain signals of other TVCs of the plurality of TVCs;
- and
- a capacitive element coupled to outputs of the plurality of TVCs to receive a combined output signal of the plurality of TVCs, the capacitive element providing an input capacitance of an analog-to-digital converter (ADC).
A device comprising:
- digital processing circuitry;
- and
- a converter comprising:
- a plurality of time-to-voltage converters (TVCs), a TVC of the plurality configured to receive an input time-domain signal, the input time-domain signal representing a different sample than input time-domain signals of other TVCs of the plurality of TVCs;
- and
- a capacitive element coupled to outputs of the plurality of TVCs to receive a combined output signal of the plurality of TVCs, the capacitive element providing an input capacitance of an analog-to-digital converter (ADC).
A method for analog-to-digital conversion, the method comprising:
- providing a calibration input to converter circuitry;
- enabling one of a plurality of time-to-voltage converters (TVCs), the plurality providing input to an analog-to-digital converter (ADC);
- measuring a response of an ADC of an array of ADCs to the one of the plurality of TVCs;
- and
- decoding the response of the ADC and providing a calibrated signal based on measured responses of the ADC to the plurality of TVCs.
