SYSTEM AND METHOD OF CALIBRATING INPUT SIGNAL TO SUCCESSIVE APPROXIMATION REGISTER (SAR) ANALOG-TO-DIGITAL CONVERTER (ADC) IN ADC-ASSISTED TIME-TO-DIGITAL CONVERTER (TDC)
SYSTEM AND METHOD OF CALIBRATING INPUT SIGNAL TO SUCCESSIVE APPROXIMATION REGISTER (SAR) ANALOG-TO-DIGITAL CONVERTER (ADC) IN ADC-ASSISTED TIME-TO-DIGITAL CONVERTER (TDC)
An apparatus and a method. The apparatus includes a counter array; a ring oscillator that is electrically coupled to the counter array, where the counter array counts a number of cycles in the ring oscillator; an analog-to-digital converter (ADC) driver that is electrically coupled to the ring oscillator; and an ADC that is electrically coupled to the ADC driver, where an output of the ADC is electrically coupled to the ring oscillator.
