# SAR Analog-to-digital converter (SAR-ADC). Although this configuration is an acceptable practice in manufacturer’s data sheets, it has the potential to create circuit performance limitations. For optimum performance, C-DAC SAR-ADCs require the correct front-end buffer and filter. The additional input filter or RC-

So this is how we design our SAR-ADC circuit from beginning to end. We will first determine what our input signal looks like in terms of the bandwidth and a full-

At low resolution, power is bounded simplicity and design specifications. SAR ADCs have a decent conversion speed (about 50kHz to 4MHz [13]) and take small overall chip area in comparison to flash ADCs, which are fast but take up a large area. SAR ADC design also flows well with the use of a serial output port due to the nature of the conversion method. A major disadvantage of SAR ADC is its design complexity and cost of production. Applications of SAR ADC As this is a most commonly used ADC, it's used for many applications like uses in biomedical devices that can be implanted in the patient, these types of ADCs are used because it consumes very less power.
