Nonlinear Applications of CCs - Current Conveyors: Variants, Applications and Hardware Implementations - page 239

A much simpler circuit capable of generating a square wave as well as rectan-
gular wave is obtainable using square wave generator of Fig. 8.25 followed by a
non-inverting integrator made from a CCII+ along with a resistor and capacitor.
This circuit was proposed in [ 23 ] by Almashary and Alhokail and is shown in
Fig. 8.28 .
The expression of the oscillation frequency of this circuit is given by the same
expression as in Eq. ( 8.39 ) for C 0 ¼ C 1 .
