Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...

Bob Pease holding court at the Analog Seminar in 2003. When I was doing the National Semiconductor Analog Seminar with Bob Pease back in 2003 (Fig. 1), I gave a talk about rail-to-rail amplifiers. I ...

There are many parameters to consider when designing a circuit using an operational amplifier (op amp) including the op-amp’s gain bandwidth (GBW) product, offset voltage and quiescent current. In ...

All operational amplifier (op-amp) datasheets have an input voltage range limitation called the common-mode range. Strictly speaking, the common-mode voltage is the average voltage on the two inputs ...
