From equation (
9.66
) it is, therefore, confirmed that the circuit can, indeed, perform
the function of a precision full wave rectifier in current mode whose output
magnitude can be controlled by control current I
con
and which is temperature
independent.
9.15 Current-Mode Multiplier/Divider Using CCCIIs
A current mode multiplier employing only two CCCIIs was proposed by
Abuelma
atti and Al-Qahtani [
46
] which is shown here in Fig.
9.47
.
Applying straight forward analysis, the output current of this circuit is given by:
