An analysis of live CMOS realizations of the current conveyor of the second
generation type (CCII) all based on the Long Tail differential Pair (LTP)
is presented and PSpice simulations are compared. The different advantages
observed in these realizations are discussed. It is also shown that the fif
th realization, which is proposed in this paper, offers an improvement in t
he bandwidth extent, which makes it suitable to operate in high frequency a
pplications.
