In minimalist amplifier design, the amp's usable frequency response needs to extend considerably beyond this (one or more octaves either side) and typically a good minimalist ... http://en.wikipedia.org/wiki/Amplifier
An operational amplifier, often called an op-amp, is a DC-coupled high-gain electronic voltage amplifier with differential inputs and, usually, a single output. http://en.wikipedia.org/wiki/Operational_amplifier

For an ideal op-amp, the inverting amplifier gain is given simply by . For equal resistors, it has a gain of -1, and is used in digital circuits as an inverting buffer. http://hyperphysics.phy-astr.gsu.edu/hbase/electronic/opampvar.html#c1
