چکیده

Four techniques for digital background calibration of SAR ADC are presented and compared. Sub-binary redundancy is the key to the realization of these techniques. Some experimental and simulation results are covered to support the effectiveness of these techniques. Keywords—SAR ADC, digital background calibration, DAC mismatch, bit weight, sub-binary redundancy

A 12bits 40MSPS SAR ADC with a redundancy algorithm and digital calibration for the ATLAS- LArg calorimeter readout

This paper presents a SAR ADC with a generalized redundant search algorithm offering the flexibility to relax the requirements on the DAC settling time and allowing a digital calibration, based on a code density analysis, to compensate the capacitors mismatching effects. The proposed architecture uses a DAC with only 2 unit capacitors, for N-bit resolution, and a simplified monotonic switching ...

Signal independent digital calibration technique for SAR ADC with one bit redundancy

A digital calibration technique for high resolution SAR ADC with only one redundant conversion bit is presented in this paper. The proposed work employs no extra calibration DAC or input signal as calibration reference. Calibration signal is generated through switching redistribution DAC in two calibration phase, so that calibration accuracy will not be affected by input signal distribution. DA...

A 12 bit 40 MSPS SAR ADC with a redundancy algorithm and digital calibration for the ATLAS LAr calorimeter readout

We present a SAR ADC with a generalized redundant search algorithm offering the flexibility to relax the requirements on the DAC settling time. The redundancy also allows a digital background calibration, based on a code density analysis, to compensate the capacitor mismatch effects. The total number of capacitors used in this architecture is limited to a half of the one in a classical SAR desi...

All-Digital Background Calibration of a Successive Approximation ADC Using the "Split ADC" Architecture

The “Split ADC” architecture enables fully digital calibration and correction of nonlinearity errors due to capacitor mismatch in a Successive Approximation (SAR) ADC. The die area of a single ADC design is split into two independent halves, each converting the same input signal. Total area and power is unchanged, resulting in minimal increase in analog complexity. For each conversion, the half...

A 10-bit 100-kS/s Successive Approximation Register ADC with improved Split Capacitor-based DAC

A 10-bit 100-kS/s successive approximation register (SAR) analogto-digital converter (ADC) with rail-to-rail input range is proposed for a low power sensor interface. It consists of a time-domain comparator, a split capacitor-based digital-to-analog converter (SC-DAC) and a SAR logic. The time-domain comparator with an offset calibration technique is used to achieve a resolution of 10-bit. To r...
