hi all
i've question about SHA.
In razavi's book, page 436 (Chap 12 Switched capacitor circuits)
there's noninverting amplifier's precision.
and noninverting amplifier exhibits greater gain error than does the unity gain sampler.
But i think unity gain sampler is fast, but less precision
and noninverting amplifier is slower but more precision
If not, why using noninverting amplifier???
mmmmm Am I wrong?
Anyone give me help please!~~~~
