As CMOS processes have improved, successive approximation conversion times have moved from tens of microseconds to microseconds. Not all technology improvements affect all types of converters; CMOS ...

The downside, of course, is the converter is relatively slow, requiring some amount of time for each bit. The input voltage also needs to stay stable over the conversion period.

This analog-to-digital converter (ADC) uses successive approximation register (SAR) architecture to achieve 12-bit resolution. The ADC includes internal sample/hold circuits, a capacitive DAC, ...

A successive approximation register ADC works by quickly cycling through all possible voltage levels in its input range, eventually zeroing in on the voltage of the input signal at that moment and ...

The successive-approximation converter is one of the oldest and most widely used types of ADC. It’s commonly found in data-acquisition, industrial-control, and instrumentation applications ...

Successive approximation register (SAR) analog-to-digital converters form a critical link between the analogue and digital realms in modern electronics.

II. ADC Architecture Figure 1 shows the ADC architecture, not including the channel multiplexors. SAR ADCs typically consist of a DAC and a comparator in a feedback loop with logic including a ...

The three most popular ADC types generally found in analog front ends are successive-approximation (a), pipelined (b), and delta-sigma (c). These block diagrams represent extremely simplified ...
