  • Patent number: 10727854
    Abstract: Described herein are apparatus and methods for realization of time interleaved digital-to-analog converters (DACs) by detecting and aligning phase mismatches. In an implementation, a N-time interleaved DAC includes N DACs and N replica DACs, where a first set of N/2 DACs operate at a clock A and a second set of N/2 DACs operate at a clock B, and where N is at least two. The phase detector generates a phase detection output by comparing outputs of the first and second set of N/2 replica DACs with a multiplexor (MUX) clock, where the MUX clock is a multiple of a frequency of the clock A or the clock B. The clock A and the clock B are aligned with the MUX clock by advancing a phase of the clock A and the clock B until the phase detection output achieves a zero crossing.

  • Patent number: 10727853
    Abstract: A DAC has a plurality DAC cells, and timing mismatch among the DAC cells can introduce errors in an output of a DAC. An efficient technique can be implemented to extract the timing error of a DAC cell. The technique involves a mixer to mix the timing error to DC (DC stands for direct current, where signal frequency is zero) and a VCO ADC to observe the output of the DAC cell to measure and extract the timing error. A first measurement is made using a first quadrature phase signal and a second measurement is made using a second quadrature phase signal. A difference between the first measurement and the second measurement yields the timing error of the DAC cell. Advantageously, the mixer can be integrated within a voltage-to-current converter of the VCO ADC. The timing error can be corrected in the digital domain or analog domain.

  • Patent number: 10715162
    Abstract: Random chopping is an effective technique for data converters. Random chopping can calibrate offset errors, calibrate offset mismatch in interleaved ADCs, and dither even order harmonics. However, the non-idealities of the (analog) chopper circuit can limit its effectiveness. If left uncorrected, these non-idealities cause severe degradation in the noise floor that defeats the purpose of chopping, and the non-idealities may be substantially worse than the non-idealities that chopping is meant to fix. To address the non-idealities of the random chopper, calibration techniques can be applied, using correlators and calibrations that may already be present for the data converter. Therefore, the cost and digital overhead are negligible. Calibrating the chopper circuit can make the chopping more effective, while relaxing the design constraints imposed on the analog circuitry.
