The proliferation of personal computers and especially video applications has created a requirement for sending high speed analog signals over twisted pair for short distances (up to 200 feet).

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 ...

One of the more common building blocks of a voltage controlled amplifier (VCA) is a differential pair amplifier. For a VCA configuration, the (top) two bases receive a control voltage for gain control ...
