Measured results show an SNDR of 47.3 dB (Nyquist input) A successive-approximation register subcircuit designed to supply an approximate digital code of Vin to the internal DAC. An internal reference DAC that, for comparison with Vref, supplies the comparator with an analog voltage equal to the digital code output of the SAR in. Animation of a 4-bit successive-approximation ADC The SAR ADC has an internal DAC, which at every clock converts the 8-bit SAR Logic output into discrete signal, which is fed into the comparator. This feedback is used to decide the next bit of the SAR output. In the project, a Charge redistribution DAC with binary weighted capacitance configuration is used. The first complete monolithic ADC was the 10-bit, 25-μs AD571 SAR ADC introduced in 1978 and designed by Paul Brokaw. Its design was based on a bipolar process with laser wafer trimmed (LWT) thin film resistors. Logic functions of the SAR ADC were implemented with integrated-injection logic (I2L).

This study introduces a novel design of 1MHz 8-bits Successive Approximation Analog-to-Digital Conversion (SAR ADC) circuit for the application of AGC (Auto-Gain Control) module within a RF (Radio Frequency) receiver channel by using 0.25 μm SOI CMOS (Silicon On Insulation, Complementary Metal Oxide Semiconductor) process. the working principle and implementation of time-interleaved SAR ADC. A test chip has been taped out in Intel22nm FFL process, containing 6 di erent versions of ADCs. In each design, a 9-bit 16-way TI-SAR ADC samples at 10GS/s with a memory block storing the digitized result from ADC.
Figure 1 shows the design of a successive-approximation ADC, at the heart of which is the successive-approximation register (SAR). The converter output is taken from this register in parallel. The SAR ADC is one of the most intuitive analog-to-digital converters to understand and once we know how this type of ADC works, it becomes apparent where its strengths and weaknesses lie.

It is known that on-chip passive charge sharing suffers from poor linearity due to the unregulated reference voltage during bit trials. This paper gives a detailed analysis for the reasons of poor linearity for passive-charge-sharing SAR ADCs
The SAR architecture allows for high-performance, low-power ADCs to be packaged in small form factors for today's demanding applications. This paper will explain how the SAR ADC operates by using a binary search algorithm to converge on the input signal.
