Layout generation for SA-ADC 52 Comparator transistor sizes Unit capacitance Common centroid placement algorithm Desired layout shape Layout template s-Component connectivity-Relative place and route CAIRO Layout generation DRC –LVS Design phase Number of capacitors and sizes Target technology Verification Parasitics Ext. Fabrication SAR ADC Considerations •Power efficiency –only comparator consumes DC power •Conversion rate typically limited by finite bandwidth of RC network during sampling and bit-tests •For high resolution, the binary weighted capacitor array can become quite large •E.g. 16-bit resolution, C total ~100pF for reasonable kT/C noise contribution low power comparator Can anyone suggest how to design a comparator for SAR ADC, aiming to achieve ultra-low power but with moderate speed? SAR can realize larger signal swing compared with pipeline ADC. Not OpAmp based, but comparator based C.Comparator Comparator used in a SAR ADC must be accurate to the Design and Implementation of a 10-bit SAR ADC Hasmayadi Abdul Majid, Rohana Musa S World Academy of Science, Engineering and Technology International Journal of Electronics and Communication Engineering Vol:7, No:10, 2013 SAR ADC V IN n C LK r V F e d C • Any DAC structure can be used • In basic structure, single comparator can be used • Performance entirely determined by S/H, DAC, and comparator • Very simple structure and relatively fast design procedure • If offset voltage of comparator is fixed, comparator offset will not introduce any nonlinearity 2020-01-01 · The comparator design for the hybrid flash-SAR ADC needs atleast (N/n)+1 times F s of the bandwidth. The number of stages and number of bits per stage ( n ) for a hybrid flash-SAR ADC is a trade-off between area and speed. power design is a fully-dynamic comparator which does not require a pre-ampliﬁer.

Matsuzawa，Titech Basic idea for low energy analog design 16 d DD s DD L s togle P V I V C I f The clocked comparators fit well into a SAR because the SAR is a clocked system. Since you are looking at using the SAR for calibration, you are not really aiming at speed and I guess you can afford to add autozeroing to your clocked comparator.

OVERALL SAR ADC SYSTEM DESIGN. The overall system of the proposed SAR ADC consists of a Sample/Hold block, a Comparator circuit, a SAR Control Logic (with some registers) and a ADC circuit. The block diagram of the proposed design is illustrated as Fig. 1.

as! the resolution (n)! increases! pipelined ADC uses several inverter-based comparators, but the measured result only shows a subcircuit with one inverter-based comparator [4].

reason, the group decided to use the SAR architecture for its 65nm ADC. This thesis describes the design port of a comparator for a SAR ADC in digital still camera and camcorder applications, from the 65nm to 0.11pm process node. The two processes have similar characteristics and both operate off a 1.2V supply.
