Abstract
Novel class-A bipolar current conveyor($CCII{\pm}$) with differential current output and its application to output current controllable CCII+ for electronic tuning systems are designed. The $CCII{\pm}$ is consists of conventional CCII+ and complementary cross current sources. The CCII+ with controllable the output current consists of the $CCII{\pm}$ and a current gain amplifier with single-ended current output. The simulation result shows that the $CCII{\pm}$ has current input impedance of $1.9{\Omega}$ and a good linearity for voltage and current follower. The proposed CCII+ has 3-dB cutoff frequency of 10MHz for the range over bias control current $100{\mu}A$ to 10mA. The range of output current control is four decade. The power dissipation of the CCII+ is 4.5mW at supply voltage of ${\pm}2.5V$.
