It has become customary in electrical engineering to think of
signal processing in terms of voltage variables to the exclusion of
current variables. This tendency has resulted in voltage signal
processing circuits such as voltage-controlled voltage sources
(VCVS) and voltage-mode operational amplifiers. However, the VCVS
operational amplifier has several limitations which prevent high
performance operation. One of these limitations is that the product
of the closed loop -3dB bandwidth and the closed loop voltage gain is
approximately a constant. Thus, for a typical internally compensated
operational amplifier the closed loop -3dB bandwidth decreases as
the closed loop voltage gain increases. By taking advantage of a
current-controlled current source (CCCS) to form a current-mode
operational amplifier, this limitation can be overcome. / Graduation date: 1991
