  • VCO-ADC with frequency-controlled switched-capacitor feedback for linearization
    Patent number: 11962316
    Abstract: An analog-to-digital converter (ADC) includes a first controlled oscillator (CO) for generating at least one phase signal, and wherein the at least one phase signal generates a first output signal of the ADC; and at least one first frequency-controlled resistor (FDR) for receiving the at least one phase signal generated by the first CO, wherein the first CO and the at least one first FDR are coupled together at a first subtraction node of the ADC, and wherein the first subtraction node receives a first input signal.
    Type: Grant
