EL2082C

Current-Mode Multiplier

Applications Information Ð Contd.

Frequency-setting resistors R are each effectively adjusted in value by an EL2082 to effect voltage-vari-

able tuning. Two gain controls yields a linear frequency adjustment; using one gives a square-root-of-

control voltage tuning. The EL2082’s could be placed in series with the integrator capacitors instead to

yield a tuning proportional to 1/Vg.

The next circuit is one of a new class of ‘‘CCII’’ filters that use the current-conveyor element. Basic

information is available in the April 1991, volume 38, number 4 edition of the IEEE Transactions on

Circuits and Systems journal, pages 456 through 461 of the article ‘‘The Single CCII Biquads with

High-Input Impedance’’, by Shen-Iuan Liu and Hen-Wai Tsao.

‘‘CCII’’ Class Filter

This interesting filter uses the current output of the EL2082 to generate a bandpass voltage output and

the intermediate node provides a second-order low-pass filter output. Both outputs should be buffered

so as not to warp characteristics, although the V of the next EL2082 can be driven directly in the case

of cascaded filters. The V

The following circuit converts a component or two-terminal network to a variable and even negative

replica of that impedance:
