The amplifier is composed of two second generationcurrent conveyors (CCII+) with common-mode input range close to supply swingsand a differential difference current conveyor (DDCC) at the second stage withhigh voltage swing at the output. Also an optional DC servo loop is employed asa feedback to second stage for the removal of any possible DC offset voltage atthe output which can be used for AC coupled applications. The simple designstrategy with high input common-mode range and nearly rail-to-rail output stagetogether with increased bandwidth advantage of current-mode approach makes theproposed implementation desirable for many of the general purposeinstrumentation applications. The design is made using 0.35μm AMS technologywith 3V supply voltage. The operation is verified by HSPICE simulations. CR - [1] S.
