A simple scheme for rail to rail op-amp operation is introduced. The input stage uses complementary differential pairs but only one pair is active at a time. It uses very compact control circuitry. Experimental verification is provided from a test chip prototype in 0.5 μm CMOS technology.

Rank-order based filters such as stack filters, multilevel and multistage median filters, morphological filters, and order statistic filters have all proven to be very effective at enhancing and restoring images. Perhaps the primary reason for their success is that they can suppress noise without destroying important image details such as edges

To my parents, who have been shown great love and support in my life, I would like to express my deepest love and thank to them.

I am going to t6.lk about RF power murcea for accelerator applications. My approach will be with particular c+omus in mind. That customers are high energy phy6icirtr who w accelerator6 66 experimental tool6 in the rtudy of the nucleus of the atom, and rpchrotron light sourea derived from electron or po6itron storage ring6. I will genually confine my6elf to electron-positron linear accelerator6 ...

− A universal and robust circuit technique to maintain a constant transconductance in rail-to-rail amplifiers, based on an input stage made up of parallelconnected complementary differential pairs, is introduced in this paper. The principle of operation consists of comparing the total transconductance with a reference value and then, appropriated tail currents are generated for the complementar...
