Title: CML IQ div/2 circuit problem? Post by hotraymanf on May 20th, 2009, 5:20pm :)I looked at out previous designed CML div/2 circuit. The sense amp and regenerative pair use the same W/L. I really don't understand this sizing. Besides, from the point of view of large signal working principle, the regenerative pair need to have gm*R greater than 1 in order for it to be latch, however, from the point of view of small signal self-oscillation freq, then the amplifier just have a negative total load resistance which does not seen to very intuitive. Thanks in advance for any kindly help! |
