As the name implies, if we finally put together all the elementary blocks above (transistors, current mirrors, current sources, differential stages and buffers) we finally come to something usable, ...

Figure 1 shows a voltage follower with one QOA and with offset adjust. Figure 1. Circuit of DC buffer-follower with paralleled QOA and with external offset adjust The four OAs are paralleled and the ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

Continuing Linear Technology’s popular series of DesignNotes is Volume 3 of Analog Circuit Design (opening figure) with over 1000 pages (and five pounds) of analog circuits. Edited by Bob Dobkin and ...

Sometimes I wish FETs had become practical before bipolar transistors. A FET is a lot more like a tube and amplifies voltages. Bipolar transistors amplify current and that makes them a bit harder to ...

Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking what parts you should keep in stock. For readers of a certain vintage, the ...

Low-voltage CMOS analog circuit design has emerged as a critical area of research, driven by the dual imperatives of energy efficiency and high-performance signal processing. This discipline focuses ...
