WebbSAR ADC design with emphasis on improving the power and area efficiency, making them a good candidate for fast, power-efficient solution for medium resolution ADCs. One of the key component that determines the overall performance of the SAR ADC is the reference buffer which drives the DAC used to measure the input signal against.
Webb9 feb. 2024 · In ADCs, performance can usually be improved using dither. This is a very small amount of random noise (e.g. white noise), which is added to the input before conversion. Its effect is to randomize the state of the LSB based on the signal. Webb1 dec. 2024 · Self-dithering technique for high-resolution SAR ADC design.
