3 . Review from last lecture. SAR AD LK IN REF DA n DA ontroller DA ontroller may be simply U/D counter Binary search controlled by Finite State Machine is faster SAR AD will have no missing codes if DA is monotone Not very fast but can be small
4 AD Types Nyquist Rate Flash Pipeline Two-Step Flash Multi-Step Flash yclic (algorithmic) Successive Approximation Folded Dual Slope Over-Sampled Single-bit Multi-bit First-order Higher-order ontinuous-time All have comparable conversion rates Basic approach in all is very similar

8 locked omparator DAk OUT IN Φ A Preamplifier with offset compensation Ideally removes all offset effects May not have a large enough gain Regenerative latch often used
9 locked omparator DAk OUT IN Φ A DAk OUT IN Φ A Preamplifier with offset compensation and regenerative latch Gain of preamplifier may still not be large enough
10 Flash AD Summary Flash AD ery fast Simple structure Usually locked Bubble Removal Important Seldom over 6 or 7 bits of resolution Flash AD has some really desirable properties (simple and fast) Wouldn t it be nice if we could derive most of the benefits of the FLASH AD without the major limitations To be practical at higher resolution, must address the major limitation of the FLASH AD Major Limitation of FLASH AD at higher resolutions? Number of comparators increases geometrically --- n
