Today the world can be considered as a small village; thanks to the existence of low power and area efficient end user terminal devices. For instance; if we considered the communication system architecture; it must include modulator/demodulator, local oscillators, filters, multipliers and variable gain amplifiers...etc. All the previously mentioned circuits are realized using basic circuits like voltage op-amps. New voltage mode circuits like differential difference amplifier and differential difference operational floating amplifier (DDOFA) were introduced for area and power optimization....
