...@ "<i>What is the real advantage of this?</i>"<br /><br />If we just look on the numbers in the CAT's papers, they are not bad at all. Indeed, there guys present 10enob/100Msps ADC having 6.2mW power consumption and 12b-10enob/50Msps ADC consuming 4.5mW power. This is quite in-line with the best alternatives.<br /><br />If comparing with column-parallel approach, one needs to add a power of analog demux and PGA to make a fair comparison.Vladimir Koifmanhttps://www.blogger.com/profile/01800020176563544699noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-55638176074186869282010-12-01T13:54:42.371+02:002010-12-01T13:54:42.371+02:00very impressive work !!!!very impressive work !!!!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-68826675544310541512010-12-01T13:26:29.888+02:002010-12-01T13:26:29.888+02:00but the precision is related to the ZCD's spee...but the precision is related to the ZCD's speed, better precision should use higher speed and more consumption. What is the real advantage of this? You can also use a dynamically biased OP-AMP.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-49775595200490025412010-12-01T12:33:23.085+02:002010-12-01T12:33:23.085+02:00This kind of power savings will increase the injec...This kind of power savings will increase the injection of spikes into the supply/ground, so it will probably generate quite some artifacts in the image. If u really want to save current without spikes use a hybrid/soft version (sure at the cost of complexity).Anonymousnoreply@blogger.com
