To realize a CCI, one more resistor needs to be connected between the non-inverting input terminal and the output of the op-amp as shown in Fig. 5, if R01 ¼ R02 ¼ 1/g the circuit realizes a CCI+. If the polarities of the input terminals of the OTA are reversed, the same circuit realizes a CCIÀ. 2 Hardware Implementations of CCs Using Off-the-Shelf ICs Fig. 4 Implementation of CCII+ and CCIIÀ proposed by Senani  Y X Fig. 5 Implementation of CCI+ and CCIÀ proposed by Senani  Y X 21 IB iy + R01 + ix iy ix − R02 + − gm − + R01 gm − iz Z IB iz Z It should be recalled that the CCII implementation by Black, Friedmann and Sedra requires an integrated circuit μA749 containing an op-amp with uncommitted output collectors, which when augmented by the introduction of several PNP and NPN transistors externally realizes a CCII.

In  presented a novel CC configuration based upon an op-amp and two OTAs which provides current gain tunability, has full compensation over temperature variation and does not suffer from the disadvantages of gain temperature dependence, input current non-linearities and CMRR effects. This circuit is shown in Fig. 10. By a routine analysis, it is easy to confirm that Vx ¼ Vy, Iy ¼ 0 IB2 =2V T IB2 2 and Iz ¼ Æ k ix. Since iixz ¼ G G1 ¼ IB1 =2V T ¼ IB1 ¼ k, it is seen that the current gain is independent of temperature.
