Abstract:

 

A differential pair-based, high-performance, first-generation current  conveyor is proposed. The proposed circuit is laid out using the Mentor  Graphics IC Station layout editor. The performance characteristics have been  determined from HSpice postlayout simulations using the Austria Mikro  Systeme 0.35 m m, 3.3 V process parameters. During the simulations, \pm  1.65 V supply voltages and a 25 m A biasing current are used. The power  consumption is about 1.12 mW. The circuit also has very high voltage swings  on ports X and Y, a very small impedance value on port X, high impedance  values on ports Y and Z, and high-valued current and voltage transfer  bandwidths. It is shown that the presented circuit can satisfy both the  low-voltage/low-power and high-frequency performance current conveyor needs  of the analog circuit applications. Furthermore, 2 new all-pass filter  circuits as application examples are given and a procedure that can be used  to search for the opportunities that would result from the use of the  modified current conveyors is presented. Some special circuit topologies and  new circuit function possibilities can be obtained by redesigning circuits  with modified current conveyors, which is not possible with a standard  current conveyor. The proposed approach is expected to allow deeper insight  into circuit synthesis using modified current conveyors.
