Abstract	:	In this thesis, the second generation current conveyor (CCII) is used in realizing new active-RC, active-R and active-C multiphase sinusoidal oscillators (MPSOs) and unity gain cell-based universal filters. Also, taking advantage of the parasitic resistance Rusd\rm\sb{x}usd which appears at the port X of the CCII, a new programmable active-C current-mode universal filter is presented. In order to be compatible with integration requirements, these circuits use minimum number of active and passive elements, enjoy independent control of the critical circuit parameters, use grounded capacitors and enjoy low active and passive sensitivities. The effects of parasitics, voltage and current tracking errors of the CCII, on the circuit parameters are discussed. Extending the use of current conveyor to nonlinear applications is investigated and a simple current-mode analog multiplier/divider circuit using only two CCCII is presented. Comparisons between all of the proposed circuits and the previously published circuits are included.
